U.S.-EU Cooperation Against Terrorism

Summary
The September 11, 2001, terrorist attacks on the United States and the subsequent revelation of
Al Qaeda cells in Europe gave new momentum to European Union (EU) initiatives to combat
terrorism and improve police, judicial, and intelligence cooperation among its member states.
Other deadly incidents in Europe, such as the Madrid and London bombings in 2004 and 2005
respectively, injected further urgency into strengthening EU counterterrorism capabilities and
reducing barriers among national law enforcement authorities so that information could be
meaningfully shared and suspects apprehended expeditiously. Among other steps, the EU has
established a common definition of terrorism and a common list of terrorist groups, an EU arrest
warrant, enhanced tools to stem terrorist financing, and new measures to strengthen external EU
border controls and improve aviation security.
As part of its drive to bolster its counterterrorism capabilities, the EU has also made promoting
law enforcement and intelligence cooperation with the United States a top priority. Washington
has largely welcomed these efforts, recognizing that they may help root out terrorist cells both in
Europe and elsewhere, and prevent future attacks against the United States or its interests abroad.
U.S.-EU cooperation against terrorism has led to a new dynamic in U.S.-EU relations by fostering
dialogue on law enforcement and homeland security issues previously reserved for bilateral
discussions. Contacts between U.S. and EU officials on police, judicial, and border control policy
matters have increased substantially since 2001. A number of new U.S.-EU agreements have also
been reached; these include information-sharing arrangements between the United States and EU
police and judicial bodies, two new U.S.-EU treaties on extradition and mutual legal assistance,
and accords on container security and airline passenger data. In addition, the United States and
the EU have been working together to curb terrorist financing and to strengthen transport security.
Nevertheless, some challenges persist in fostering closer U.S.-EU cooperation in these fields.
Among the most prominent and long-standing are data privacy and data protection issues. The
EU considers the privacy of personal data a basic right and EU rules and regulations strive to
keep personal data out of the hands of law enforcement as much as possible. Over the years, the
negotiation of several U.S.-EU information-sharing agreements, from those related to tracking
terrorist financial data to sharing airline passenger information, has been complicated by EU
concerns about whether the United States could guarantee a sufficient level of protection for
European citizens’ personal data. EU worries about U.S. data protection safeguards and practices
have been further heightened by the public revelations in June 2013 of U.S. National Security
Agency (NSA) surveillance programs and news reports alleging that U.S. intelligence agencies
have monitored EU diplomatic offices and computer networks. Other issues that have led to
periodic tensions include detainee policies, differences in the U.S. and EU terrorist designation
lists, and balancing measures to improve border controls and border security with the need to
facilitate legitimate transatlantic travel and commerce.
Congressional decisions related to improving border controls and transport security, in particular,
may affect how future U.S.-EU cooperation evolves. In addition, given the European Parliament’s
growing influence in many of these policy areas, Members of Congress may be able to help shape
Parliament’s views and responses through ongoing contacts and the existing Transatlantic
Legislators’ Dialogue (TLD). This report examines the evolution of U.S.-EU counterterrorism
cooperation and the ongoing challenges that may be of interest in the 113th Congress.

U.S.-EU Cooperation Against Terrorism

Background on European Union Efforts
Against Terrorism

The September 11, 2001, terrorist attacks on the United States and the subsequent revelation of
Al Qaeda cells in Europe gave new momentum to European Union (EU) initiatives to combat
terrorism and improve police, judicial, and intelligence cooperation. The EU is a unique
partnership that defines and manages economic and political cooperation among its current 28
member states.1 The EU is the latest stage in a process of European integration begun in the
1950s to promote peace and economic prosperity throughout the European continent. As part of
this drive toward further European integration, the EU has long sought to harmonize policies
among its members in the area of “justice and home affairs” (or JHA). Efforts in the JHA field are
aimed at fostering common internal security measures while protecting the fundamental rights of
EU citizens and promoting the free movement of persons within the EU.
Among other policy areas, JHA encompasses countering terrorism and cross-border crimes,
police and judicial cooperation, border controls, and immigration and asylum issues. For many
years, however, EU attempts to forge common JHA policies were hampered by member state
concerns that doing so could infringe on their national legal systems and national sovereignty.
Insufficient resources and a lack of trust among member state law enforcement agencies also
impeded progress in the JHA area.
The 2001 terrorist attacks changed this status quo and served as a wake-up call for EU leaders
and member state governments. In the weeks after the attacks, European law enforcement efforts
to track down terrorist suspects and freeze financial assets—often in close cooperation with U.S.
authorities—produced numerous arrests, especially in Belgium, France, Germany, Italy, Spain,
and the United Kingdom. Germany and Spain were identified as key logistical and planning bases
for the attacks on the United States. As a result, European leaders recognized that the EU’s largely
open borders and Europe’s different legal systems enabled some terrorists and other criminals to
move around easily and evade arrest and prosecution. For example, at the time of the 2001
attacks, most EU member states lacked anti-terrorist legislation, or even a legal definition of
terrorism. Without strong evidence that a suspect had committed a crime common to all countries,
terrorists or their supporters were often able to avoid apprehension in one EU country by fleeing
to another with different laws and criminal codes. Moreover, although suspects could travel
among EU countries quickly, extradition requests often took months or years to process.
Since the 2001 attacks, the EU has sought to speed up its efforts to harmonize national laws and
bring down barriers among member states’ law enforcement authorities so that information can be
meaningfully shared and suspects apprehended expeditiously. Among other steps, the EU has
established a common definition of terrorism and a list of terrorist groups, an EU arrest warrant,
enhanced tools to stem terrorist financing, and new measures to strengthen external EU border
controls and improve aviation security. The EU has been working to bolster Europol, its joint

criminal intelligence body, and Eurojust, a unit charged with improving prosecutorial
coordination in cross-border crimes in the EU.
The March 2004 terrorist bombings in Madrid and the July 2005 attacks on London’s metro
system injected a greater sense of urgency into EU counterterrorism efforts, and gave added
impetus to EU initiatives aimed at improving transport security, impeding terrorist travel, and
combating Islamist extremism. In the wake of the Madrid attacks, the EU created the position of
Counterterrorist Coordinator. Key among the Coordinator’s responsibilities are enhancing
intelligence-sharing among EU members and promoting the implementation of already agreed
EU anti-terrorism policies, some of which have bogged down in the legislative processes of
individual member states. Following the London attacks, the EU adopted a new counterterrorism
strategy outlining EU goals to “prevent, protect, pursue, and respond to the international terrorist
threat,” as well as a plan to combat radicalization and terrorist recruitment.2
Over the last several years, the EU has continued working to strengthen its counterterrorism
capabilities and further improve police, judicial, and intelligence cooperation among its member
states. In 2008, the EU expanded its common definition of terrorism to include three new
offenses: terrorist recruitment, terrorist training, and public provocation to commit terrorism,
including via the Internet. Among other recent initiatives, the EU has been seeking to improve the
security of explosives and considering the development of an EU-wide system for the exchange
of airline passenger data. In 2010, the EU issued its first-ever internal security strategy, which
highlights terrorism as a key threat facing the EU and aims to develop a coherent and
comprehensive EU strategy to tackle not only terrorism, but also a wide range of organized
crimes, cybercrime, money laundering, and natural and man-made disasters.
Despite the death of Al Qaeda leader Osama bin Laden in Pakistan in May 2011, many terrorism
experts expect that the “Al Qaeda narrative” will likely continue to attract both European and
non-European followers. The July 2012 terrorist attack on Israeli tourists in Bulgaria, which
Bulgarian authorities have linked to the Lebanese Shiite Hezbollah organization, serves as a stark
reminder that Europe remains vulnerable to terrorist activity perpetrated by a number of groups in
addition to Al Qaeda. EU policymakers are also increasingly worried about reports of European
citizens being recruited to fight with rebels in Syria, especially with Islamist extremist groups,
and concerned about the potential danger such trained militants might pose should they
eventually return to Europe. Amid these various threats, EU officials assert that continued
vigilance and enhanced cooperation against terrorism remains essential.
Most observers view the EU as having made rapid progress since 2001 on forging political
agreements on many counterterrorism initiatives and others in the JHA field that had been
languishing for years. Indeed, the pace has been speedy for the EU, a traditionally slow-moving
body because of its intergovernmental nature and largely consensus-based decision-making
processes. Until recently, most decisions in the JHA field required the unanimous agreement of all
EU member states. However, the EU’s latest institutional reform treaty—the Lisbon Treaty, which
entered into force in December 2009—allows member states to use a qualified majority voting
system for most JHA decisions in a bid to strengthen JHA further and speed EU decision-making.
In practice, experts say that EU member states will likely still seek consensus as much as possible

on sensitive JHA policies, such as those related to countering terrorism. The Lisbon Treaty also
strengthens the role of the European Parliament (EP), a key EU institution currently composed of
766 directly-elected members, in JHA policy-making by giving it the right to approve or reject
most JHA-related legislation.3
Despite the political commitment of EU leaders to promote cooperation in the JHA field and to
improve the EU’s collective ability to better combat terrorism, forging common internal security
policies has been challenging. Implementation of EU policies in the JHA field is up to the
member states, and considerable lag times may exist between when an agreement is reached in
Brussels and when it is implemented at the national level. In addition, EU member states retain
national control over their law enforcement and judicial authorities, and some national police and
intelligence services remain reluctant to share information with each other. Consequently, efforts
to promote greater EU-wide cooperation against terrorism and other cross-border crimes remain
works in progress.
U.S.-EU Counterterrorism Cooperation:
Progress to Date and Ongoing Challenges

As part of the EU’s efforts to combat terrorism since September 11, 2001, the EU made
improving law enforcement and intelligence cooperation with the United States a top priority. The
previous George W. Bush Administration and many Members of Congress largely welcomed this
EU initiative in the hopes that it would help root out terrorist cells in Europe and beyond that
could be planning other attacks against the United States or its interests. Such growing U.S.-EU
cooperation was in line with the 9/11 Commission’s recommendations that the United States
should develop a “comprehensive coalition strategy” against Islamist terrorism, “exchange
terrorist information with trusted allies,” and improve border security through better international
cooperation. Some measures in the resulting Intelligence Reform and Terrorism Prevention Act of
2004 (P.L. 108-458) and in the Implementing Recommendations of the 9/11 Commission Act of
2007 (P.L. 110-53) mirrored these sentiments and were consistent with U.S.-EU counterterrorism
efforts, especially those aimed at improving border controls and transport security.
U.S.-EU cooperation against terrorism has led to a new dynamic in U.S.-EU relations by fostering
dialogue on law enforcement and homeland security issues previously reserved for bilateral
discussions. Despite some frictions, most U.S. policymakers and analysts view the developing
partnership in these areas as positive. Like its predecessor, the Obama Administration has
supported U.S. cooperation with the EU in the areas of counterterrorism, border controls, and
transport security. At the November 2009 U.S.-EU Summit in Washington, DC, the two sides
reaffirmed their commitment to work together to combat terrorism and enhance cooperation in
the broader JHA field. In June 2010, the United States and the EU adopted a new “Declaration on
Counterterrorism” aimed at deepening the already close U.S.-EU counterterrorism relationship

3 The Lisbon Treaty also adds an “emergency brake” that allows any member state to halt certain JHA measures it
views as threatening its national legal system, and ultimately, to opt out. Despite these safeguards, the UK and Ireland
essentially negotiated the right to choose those JHA policies they want to take part in and to opt out of all others;
Denmark extended its existing opt-out in some JHA areas to all JHA issues. The Lisbon Treaty technically renames
JHA as the “Area of Freedom, Security, and Justice,” although JHA remains the more commonly-used term. For more

Treaty

and highlighting the commitment of both sides to combat terrorism within the rule of law. In June
2011, President Obama’s National Strategy for Counterterrorism asserted that in addition to
working with European allies bilaterally, “the United States will continue to partner with the
European Parliament and European Union to maintain and advance CT efforts that provide
mutual security and protection to citizens of all nations while also upholding individual rights.”
Nevertheless, some challenges remain in the evolving U.S.-EU counterterrorism relationship.
Among the most prominent are long-standing data privacy and data protection concerns, which
have complicated a range of U.S.-EU information-sharing agreements. Other issues that have led
to periodic tensions include detainee policies, differences in the U.S. and EU terrorist designation
lists, and balancing measures to improve border controls and border security with the need to
facilitate legitimate transatlantic travel and commerce.
Developing U.S.-EU Links
Contacts between U.S. and EU officials—from the cabinet level to the working level—on police,
judicial, and border control policy matters have increased substantially since 2001, and have
played a crucial role in developing closer U.S.-EU ties. The U.S. Departments of State, Justice,
Homeland Security, and the Treasury have been actively engaged in this process.4 The Secretary
of State, U.S. Attorney General, and Secretary of Homeland Security meet at the ministerial level
with their respective EU counterparts at least once a year, and a U.S.-EU working group of senior
officials meets once every six months to discuss police and judicial cooperation against terrorism.
In addition, the United States and the EU have developed a regular dialogue on terrorist financing
and have established a high-level policy dialogue on border and transport security to discuss
issues such as passenger data-sharing, cargo security, biometrics, visa policy, and sky marshals.
Over the last few years, U.S. and EU officials have also engaged in expert-level dialogues on
critical infrastructure protection and resilience, and preventing violent extremism.
U.S. and EU agencies have also established reciprocal liaison relationships. Europol has posted
two liaison officers in Washington, DC, and the United States has stationed an FBI officer in The
Hague, Netherlands, to work with Europol on counterterrorism. A U.S. Secret Service liaison
posted in The Hague also works with Europol on counterfeiting issues. In 2006, a U.S. liaison
position was established at Eurojust headquarters in The Hague as part of a wider U.S.-Eurojust
agreement to facilitate cooperation between European and U.S. prosecutors on terrorism and
other cross-border criminal cases.
New Law Enforcement and Intelligence Cooperation Agreements
U.S.-EU efforts against terrorism have produced a number of new accords that seek to improve
police and judicial cooperation. In 2001 and 2002, two U.S.-Europol agreements were concluded
to allow U.S. law enforcement authorities and Europol to share both “strategic” information
(threat tips, crime patterns, and risk assessments) as well as “personal” information (such as
names, addresses, and criminal records). U.S.-EU negotiations on the personal information accord

4 On the U.S. side, the State Department has the lead in managing the interagency policymaking process toward
enhancing U.S.-EU police, judicial, and border control cooperation, while the Justice and Homeland Security
Departments provide the bulk of the legal and technical expertise. The Treasury Department has the lead on efforts to
suppress terrorist financing.

proved especially arduous, as U.S. officials had to overcome worries that the United States did
not meet EU data protection standards. The EU considers the privacy of personal data a basic
right, and EU regulations are written to keep such data out of the hands of law enforcement
authorities as much as possible. EU data protection concerns also reportedly slowed negotiations
over the 2006 U.S.-Eurojust cooperation agreement noted above. In 2007, the United States and
the EU also signed an agreement that sets common standards for the security of classified
information to facilitate the exchange of such information.
In 2010, two new U.S.-EU-wide treaties on extradition and mutual legal assistance (MLA)
entered into force following their approval by the U.S. Senate and the completion of the
ratification process in all EU member states.5 These treaties, signed by U.S. and EU leaders in
2003, seek to harmonize the bilateral accords that already exist between the United States and
individual EU members, simplify the extradition process, and promote better information-sharing
and prosecutorial cooperation. Washington and Brussels hope that these two agreements will be
useful tools in combating not only terrorism, but other transnational crimes such as financial
fraud, organized crime, and drug and human trafficking.
In negotiating the extradition and MLA agreements, the U.S. death penalty and the extradition of
EU nationals posed particular challenges. Washington effectively agreed to EU demands that
suspects extradited from the EU will not face the death penalty, which EU law bans. U.S. officials
also relented on initial demands that the treaty guarantee the extradition of any EU national. They
stress, however, that the extradition accord modernizes existing bilateral agreements with
individual EU members, streamlines the exchange of information and transmission of documents,
and sets rules for determining priority in the event of competing extradition requests between the
United States and EU member states. The MLA treaty will provide U.S. authorities access to
European bank account and financial information in criminal investigations, speed MLA request
processing, allow the acquisition of evidence (including testimony) by video conferencing, and
permit the participation of U.S. authorities in joint EU investigations.6
Despite these growing U.S.-EU ties and agreements in the law enforcement area, some U.S.
critics continue to doubt the utility of collaborating with EU-wide bodies given good existing
bilateral relations between the FBI and CIA (among other agencies) and national police and
intelligence services in EU member states. Many note that Europol lacks enforcement
capabilities, and that its effectiveness to assess and analyze terrorist threats and other criminal
activity largely depends on the willingness of national services to provide it with information.
Meanwhile, European officials complain that the United States expects intelligence from others,
but does not readily share its own. Others contend that European opposition to the U.S. death
penalty or resistance to handing over their own nationals may still slow or prevent the timely
provision of legal assistance and the extradition of terrorist suspects in some cases.

5 In September 2006, former U.S. President George W. Bush transmitted the U.S.-EU treaties on extradition and MLA
to the Senate for its advice and consent, along with separate bilateral instruments signed by the United States and
individual EU member states that reconciled the terms of existing bilateral extradition and MLA treaties with the new
EU-wide treaties. The Senate gave its advice and consent in September 2008. All EU member states also had to
transpose the terms of the U.S.-EU extradition and MLA accords into their national laws. Following the completion of
this process in all EU members, the United States and the EU exchanged the instruments of ratification for both
agreements in October 2009, thus allowing them to enter into force in February 2010.

U.S.-EU Cooperation Against Terrorism

Tracking and Suppressing Terrorist Financing
The United States and the EU have been active partners in efforts to track and stem terrorist
financing. The two sides cooperate frequently in global forums, such as the United Nations and
the intergovernmental Financial Action Task Force, to suppress terrorist financing and to improve
international financial investigative tools. The United States and the EU both benefit from an
agreement that allows U.S. authorities access to financial data held by a Belgian-based
consortium of international banks—known as SWIFT, or the Society for Worldwide Interbank
Financial Telecommunications—as part of the U.S. Treasury Department’s Terrorist Finance
Tracking Program (TFTP). U.S. authorities have shared over 1,800 leads resulting from the
SWIFT data with European governments, and U.S. and EU officials assert that many of these
leads have helped in the prevention or investigation of terrorist attacks in Europe.7 However, the
TFTP and the U.S.-EU agreement permitting the sharing of SWIFT data remains controversial in
Europe due to ongoing data privacy concerns. (For more information on the U.S.-EU SWIFT
agreement, see “Promoting Information-Sharing and Protecting Data Privacy” below).
Designating Terrorist Individuals and Groups
U.S. and EU officials have worked together successfully since 2001 to bridge many gaps in their
respective lists of individuals and groups that engage in terrorist activities, viewing such efforts as
important in terms of symbolically presenting a united U.S.-EU front, and in helping to stem
terrorist financing. For all those named on the EU’s “common terrorist list” or “blacklist,” which
contains individuals and entities based both in Europe and worldwide, EU members must assist
each other in related police investigations and legal proceedings. In addition, for those individuals
and entities based outside EU territory (such as Hamas), all EU member states are legally
obligated to freeze the assets of those named and ensure that financial resources are not made
available to them (within EU jurisdiction).8
In order for a person or entity to be added to (or deleted from) the EU’s common terrorist list,
there must be unanimous agreement among all EU member states. Over the last decade, the
United States and other countries have successfully lobbied the EU to add several organizations—
such as the Turkish-based Kurdistan Worker’s Party (PKK), the Revolutionary Armed Forces of
Colombia (FARC), and some Palestinian groups—to the EU’s common terrorist list. The United
States has also taken some cues from the EU and has included a number of members of the
Basque separatist group ETA, among others, to its terrorist designation lists.9
Nevertheless, a few differences in the U.S. and EU terrorist designation lists persist. For example,
the EU remains hesitant about adding some suspected Hamas-related charities to its common

7 U.S. Department of the Treasury, “Terrorist Finance Tracking Program: Questions and Answers,” available at
http://www.ustreas.gov.
8 Although individuals and groups based within EU territory that have been designated as “terrorist” (such as the Real
IRA or the Italian anarchist Red Brigades) are subject only to the common list’s strengthened police cooperation
measures, member state governments generally seek to apply their own financial sanctions to such “internal” or
“domestic” persons or organizations. See Paul Ames, “EU Adopts Anti-terrorist Measures,” Associated Press,
December 28, 2001. The EU also maintains a separate terrorist list against persons and entities associated with Al
Qaeda and the Taliban that essentially enacts into EU law the post- 9/11 U.N. Security Council sanctions against these
individuals and groups.

terrorist list because some EU members view them as separate entities engaged in political or
social work.10 And some charities that the United States has designated as fronts for Hamas, such
as the UK-based Interpal, have been investigated by European national authorities but have been
cleared of funding Hamas terrorist activities. Given that such charities have passed scrutiny at the
national level, it is unlikely that EU governments would agree to blacklist them at the EU level.11
For many years, EU member states were also divided on whether the Lebanese-based Hezbollah
organization should be included on the EU’s common terrorist list. The United States considers
Hezbollah, which is backed by Syria and Iran, to be a foreign terrorist organization and applies
financial and other sanctions to the group and its members. While some EU member states, such
as the United Kingdom and the Netherlands, had long supported adding either all or part of
Hezbollah to the EU’s common list, France and other members had opposed doing so.
Traditionally, EU members that were hesitant about putting Hezbollah on the EU’s common list
argued that it would be counterproductive to managing relations with Lebanon given Hezbollah’s
role in the Lebanese government and its representation in Lebanon’s parliament. Some EU
member states were also apparently reluctant to add Hezbollah to the EU’s list because they
viewed Hezbollah as providing needed social services in some of Lebanon’s poorest
communities. On the other hand, critics of Hezbollah’s absence from the EU’s list contended that
Hezbollah was responsible for numerous terrorist attacks in the Middle East and elsewhere, and
that Hezbollah had long used Europe as a primary base for fundraising and financial services.
Those in favor of including Hezbollah on the EU’s list also noted that Hezbollah leaders
themselves reportedly admitted that if the EU were to blacklist the group, it would have serious
negative implications for Hezbollah’s financial and moral support in Europe.12
Over the last two years, several events led to a renewed debate within the EU on Hezbollah, and
to repeated U.S. (and Israeli) calls for the EU to add Hezbollah to its common terrorist list. These
included the July 2012 bombing at an airport in Burgas, Bulgaria (in which five Israeli tourists
and their Bulgarian bus driver were killed) that Bulgarian authorities publically linked to
Hezbollah, as well as the March 2013 conviction in Cyprus of a Hezbollah operative (with dual
Lebanese-Swedish citizenship) involved in planning attacks on Israeli tourists there. In addition,
Hezbollah’s increased profile in lending active military and logistical support to the Syrian
government of Bashar al Asad, despite the regime’s violent response to the popular uprising and
civil war, heightened concerns about the group and prompted further appeals—both from within
and outside Europe—urging EU action against Hezbollah.
By late spring 2013, it appeared that a consensus was forming among EU member states to put
Hezbollah’s military wing on the EU’s terrorist list, but not the entire Hezbollah organization.
Many observers viewed this as a “compromise” position that would be more amenable to those

10 The EU has listed Hamas’ military wing on its common terrorist list since 2001, and its political wing since 2003. In
addition, the EU common terrorist list includes three charities that are believed to be related to Hamas: the U.S.-based
Holy Land Foundation for Relief and Development; Stichting Al Aqsa (or Al Aqsa Netherlands); and Al-Aqsa, e.V. (or
the Al-Aqsa Foundation), located throughout Europe.
11 Of 11 charities currently designated by the United States as front organizations for Hamas, five are based primarily in
Europe (including Al-Aqsa, e.V.). For more information, see U.S. Treasury Department, http://www.treasury.gov/

EU members still concerned that adding all of Hezbollah could destabilize Lebanon and reduce
the EU’s influence in the region. In late July 2013, the EU announced that its 28 member states
had agreed to add Hezbollah’s military wing to its common terrorist list. In adopting this decision,
however, the EU also asserted that doing so “does not prevent the continuation of dialogue with
all political parties in Lebanon,” nor the “legitimate transfers to Lebanon and the delivery of
assistance, including humanitarian assistance, from the European Union and its Member States in
Lebanon.”13 With this statement, the EU sought to underline that its decision to add Hezbollah’s
military wing to its terrorist list would not preclude the EU’s ability to interact with Lebanon’s
current caretaker government, which includes two ministers associated with Hezbollah.
Many analysts judge that some of the most important implications of the EU’s decision may be
largely symbolic, in terms of sending Hezbollah a message that the EU will not tolerate terrorist
attacks within its borders and that the organization’s terrorist activities will endanger any
legitimacy it may have as a political and social actor. Some experts hope that the EU designation
will spur EU governments to initiate or enhance intelligence investigations into activities that
may be tied to Hezbollah’s military wing, and thus make Europe a far less attractive base of
operations for Hezbollah. Nevertheless, critics contend that listing only Hezbollah’s military wing
is insufficient because Hezbollah would still be allowed to fundraise in Europe. Those of this
view argue that there is no meaningful distinction between Hezbollah’s political and military
wings, and note that the EU has not provided authoritative guidance on how to distinguish
between what it views as these two wings.14
Successive U.S. Administrations and many Members of Congress have long urged the EU to
include Hezbollah on its common terrorist list. Following Bulgaria’s announcement in February
2013 implicating Hezbollah in the Burgas bombing, the Obama Administration called on Europe
“to take proactive action to uncover Hezbollah’s infrastructure and disrupt the group’s financing
schemes and operational networks in order to prevent future attacks.”15 In the wake of the Burgas
bombing, individual Members and groups of Members, in both the House and Senate, sent
several letters to EU officials and institutions calling upon the EU to add Hezbollah to its terrorist
list. At the end of the 112th Congress, the Senate passed S.Res. 613 in December 2012, and the
House passed H.Res. 834 in January 2013, both of which called on the governments of Europe
and the EU to designate Hezbollah as a terrorist organization and to impose sanctions. The
Obama Administration and many Members of Congress have welcomed the EU’s decision to put
Hezbollah’s military wing on its common terrorist list as a positive step.16

U.S.-EU Cooperation Against Terrorism

Promoting Information-Sharing and Protecting Data Privacy
Although the United States and the EU both recognize the importance of sharing information in
an effort to track and disrupt terrorist activity, data privacy has been and continues to be a key
U.S.-EU sticking point. As noted previously, the EU considers the privacy of personal data a
basic right; EU data privacy regulations set out common rules for public and private entities in the
EU that hold or transmit personal data, and prohibit the transfer of such data to countries where
legal protections are not deemed “adequate.” In the negotiation of several U.S.-EU information-
sharing agreements, from those related to Europol to SWIFT to airline passenger data, some EU
officials have been concerned about whether the United States could guarantee a sufficient level
of protection for European citizens’ personal data. In particular, some Members of the European
Parliament (MEPs) and many European civil liberty groups have long argued that elements of
U.S.-EU information-sharing agreements violate the privacy rights of EU citizens.
In light of the public revelations in June 2013 of U.S. National Security Agency (NSA)
surveillance programs and news reports alleging that U.S. intelligence agencies have monitored
EU diplomatic offices and computer networks, many analysts are worried about the future of
U.S.-EU information-sharing arrangements. As discussed in this section, many of these U.S.-EU
information-sharing agreements require the approval of the European Parliament, and many
MEPs (as well as many officials from the European Commission and the national governments)
have been deeply dismayed by the NSA programs and other spying allegations. In response, the
Parliament passed a resolution expressing serious concerns about the U.S. surveillance operations
and established a special working group to conduct an in-depth investigation into the reported
programs.17 In addition, led by the European Commission and the U.S. Department of Justice, the
United States and the EU have convened a joint expert group on the NSA’s surveillance
operations, particularly the so-called PRISM program (in which the NSA reportedly collected
data from leading U.S. Internet companies), to assess the “proportionality” of such programs and
their implications for the privacy rights of EU citizens.18
U.S. officials have sought to reassure their EU counterparts that the PRISM program and other
U.S. surveillance activities operate within U.S. law and are subject to oversight by all three
branches of the U.S. government. Some observers note that the United States has been striving to
demonstrate that it takes EU concerns seriously and is open to improving transparency, in part to
maintain European support for existing information-sharing accords, such as SWIFT (which will
be up for renewal in 2015), and the U.S.-EU Passenger Name Record agreement (up for renewal
in 2019). Nevertheless, many experts predict that the revelations of programs such as PRISM will
make the negotiation of future U.S.-EU information-sharing arrangements more difficult, and
may make the European Parliament even more cautious and skeptical about granting its approval.
The revelation of the NSA programs and the other spying allegations have also led some MEPs to
demand that EU data protection reforms, which have been under discussion in the EU since
January 2012, should include even stronger safeguards than those initially proposed for personal

data transferred outside the EU, including to the United States. Some U.S. officials are concerned
that such changes to EU data protection rules could call into question existing bilateral
agreements governing the processing and sharing of personal data between U.S. law enforcement
authorities and their counterparts in EU member states. Many U.S. policymakers also worry that
stronger EU data protection measures could be overly burdensome for U.S. businesses, especially
those in the digital and telecommunications industries that are heavily engaged in providing
Internet and other related services in Europe.19
The U.S.-EU SWIFT Accord
Controversy over Europe’s role in the U.S. Terrorist Finance Tracking Program surfaced
originally in 2006, following press reports that U.S. authorities had been granted secret access to
SWIFT financial data since 2001. In an attempt to assure Europeans that their personal data was
being protected, U.S. officials asserted that SWIFT data was used only for counterterrorism
purposes, was obtained by the U.S. Treasury Department by administrative subpoena, and that no
data mining occurred as part of the TFTP. In June 2007, the United States and the EU reached a
deal to allow continued U.S. access to SWIFT data for counterterrorism purposes, but it remained
worrisome for some European politicians and privacy groups.20
In 2009, changes to SWIFT’s systems architecture—including a reduction in the amount of data
stored on U.S. servers and the transfer of a large portion of data critical to the TFTP to a storage
location in Europe—necessitated a new U.S.-EU agreement to permit the continued sharing of
SWIFT data with the U.S. Treasury Department. In November 2009, the European Commission
(the EU’s executive) reached a new accord with the United States on SWIFT. However, under the
EU’s new Lisbon Treaty, the European Parliament gained the right to approve or reject
international agreements such as the SWIFT accord by majority vote. In February 2010, the
Parliament rejected this new version of the U.S.-EU SWIFT agreement by a vote of 378 to 196
(with 31 abstentions); those MEPs who opposed the accord claimed that it did not contain
sufficient protections to safeguard the personal data and privacy rights of EU citizens. Given the
EP’s long-standing concerns about SWIFT and the TFTP, many observers were not surprised that
some MEPs took the opportunity to both assert the Parliament’s new powers and to halt U.S.
access to much of the SWIFT data until their views regarding the protection of data privacy and
civil liberties were taken on board more fully.
In May 2010, the European Commission and U.S. authorities began negotiating a revised U.S.-
EU SWIFT agreement that could garner the necessary EP support for approval. Two key EP
concerns related to guaranteeing judicial remedy for European citizens in the United States in the
event of possible data abuse, and the use of “bulk data” transfers. Many MEPs wanted more
targeted transfers and less data included in any transfer, but U.S. and EU officials contended that
such “bulk” transfers were essentially how the SWIFT system worked and had to be maintained
for technical reasons. Some MEPs also called for greater supervision by an “appropriate EU-
appointed authority” over U.S. access to SWIFT data.21

U.S.-EU Cooperation Against Terrorism

In mid-June 2010, U.S. and EU officials concluded a new draft SWIFT agreement. Among other
provisions, the draft provided for the possibility of administrative and legal redress for EU
citizens in the United States and gave Europol the authority to approve or reject U.S. Treasury
Department requests for SWIFT data. Press reports indicated, however, that some MEPs were still
unhappy with several of the draft’s provisions. In order to avoid another “no” vote by the EP, EU
and U.S. officials reportedly agreed to two additional changes to the draft: effectively
guaranteeing that an independent observer appointed by the European Commission would be
based in Washington, DC, to oversee, along with SWIFT personnel, the extraction of SWIFT
data; and requiring the European Commission to present plans for an EU equivalent to the U.S.
TFTP within a year. Such a “European TFTP” would be aimed at enabling the EU to extract
SWIFT data on European soil and send the targeted results onward to U.S. authorities, thereby
avoiding “bulk data” transfers to the United States in the longer term.22
The EP approved the latest iteration of the U.S.-EU SWIFT accord on July 8, 2010, by 484 votes
to 109 (with 12 abstentions). The agreement entered into force on August 1, 2010, for a period of
five years. Some MEPs, however, continue to be concerned about the EU’s role in the U.S. TFTP
and whether the SWIFT accord is being properly implemented. Several MEPs, for example, have
criticized Europol for too readily approving vague U.S. requests for SWIFT data. As part of a
review of the U.S.-EU SWIFT agreement released in March 2011, the European Commission
recommended certain measures to help make the TFTP more transparent, including by providing
more information to Europol in writing. In December 2012, the Commission released the results
of a second review of the agreement. This second review concluded that the TFTP has provided
concrete benefits in the fight against terrorism (including for EU countries), that the agreement’s
safeguards were being properly implemented, and that the recommendations presented in the first
review report of 2011 had been followed up to a large extent.23
As part of the new SWIFT accord, the United States pledged its support and assistance in the
event of an EU decision to develop its own terrorist finance tracking program and promised
further consultations with the EU to determine whether the existing U.S.-EU SWIFT agreement
might need to be adjusted as a result. In July 2011, the European Commission issued a
preliminary study with several options for establishing what it has termed a European Terrorist
Finance Tracking System (TFTS). According to a Commission press release, a European TFTS
would have two main objectives: to limit the amount of personal data transferred to the United
States; and to contribute significantly to stemming terrorist financing.24 U.S. officials will likely
be keen to ensure that any eventual European TFTS does not compromise the operational
effectiveness of the U.S.-EU SWIFT agreement.

U.S.-EU Cooperation Against Terrorism

EU development of a European TFTS, however, may face significant challenges. The
Commission has not yet put forth a concrete legislative proposal on the TFTS, and any such
proposal must ultimately be approved by both the member states and the EP. Some observers
point out that member state and EP agreement on a European TFTS may be difficult given the
technical complexities involved and differing views between and among the member states and
the EP on its purpose and scope. Some member states and MEPs have also expressed concerns
about the potential costs of such a system. Others are skeptical about the implementation of an
eventual European TFTS, noting that it would likely entail more intelligence-sharing among EU
member states, which some members and national intelligence services have long resisted.25
Passenger Name Record (PNR) Data
In May 2004, the United States and EU reached an initial agreement permitting airlines operating
flights to or from the United States to provide U.S. authorities with passenger name record (PNR)
data in their reservation and departure control systems within 15 minutes of a flight’s departure
(in order to comply with provisions in the U.S. Aviation and Transportation Security Act of 2001,
P.L. 107-71). This accord was controversial in Europe because of fears that it violated the privacy
rights of EU citizens and did not contain sufficient protections to safeguard their personal data. As
a result, the European Parliament lodged a case against the PNR agreement in the EU Court of
Justice; in May 2006, the Court annulled the PNR accord on grounds that it had not been
negotiated on the proper legal basis. EU officials stressed, however, that the Court did not rule
that the agreement infringed on European privacy rights.
In July 2007, the United States and the EU concluded negotiations on a new, seven-year
agreement to ensure the continued transfer of PNR data. U.S. officials appeared pleased with
several provisions of this new deal, such as allowing the U.S. Department of Homeland Security
to share PNR data with other U.S. agencies engaged in the fight against terrorism; extending the
length of time that the United States could store such data (from 3½ to 15 years ultimately); and
permitting the United States to access sensitive information about a passenger’s race, ethnicity,
religion, and health in exceptional circumstances. The new accord also required airlines to send
data from their reservation systems to U.S. authorities at least 72 hours before a flight’s departure.
The United States agreed, however, to reduce the number of fields from which data would be
collected, from 34 to 19.26
Although the 2007 U.S.-EU PNR agreement was provisionally in force since its signing, the
European Parliament had to approve it in order for the accord to be formally signed and remain in
force. Many MEPs, however, objected to key elements of the 2007 agreement, including the
amount of PNR data transferred; the length of time such data could be kept; and what they
viewed as an inadequate degree of redress available for European citizens for possible data
misuse. Some MEPs also worried that U.S. authorities might use PNR data for “data mining” or
“data profiling” purposes. At the same time, many MEPs recognized that rejecting the U.S.-EU
PNR agreement would create legal uncertainties and practical difficulties for both travelers and
air carriers. As such, in May 2010, the EP agreed to postpone its vote on the 2007 PNR deal,
calling instead upon the European Commission to present a “global external PNR strategy”
setting out general requirements for all EU PNR agreements with other countries; the EP

essentially expected that the EU PNR deal with the United States (as well as similar EU
agreements on PNR data pending with Australia and Canada) would be renegotiated to conform
to the new PNR standards put forth by the Commission.27
In September 2010, the European Commission issued its “global external PNR strategy”28 and
called for the renegotiation of the EU’s PNR agreements with the United States, Australia, and
Canada. Among other general principles proposed in the “external PNR strategy,” the
Commission asserted that PNR data should be used exclusively to combat terrorism and other
serious transnational crimes, passengers should be given clear information about the exchange of
their PNR data and have the right to effective administrative and judicial redress, and that a
decision to deny a passenger the right to board an airplane must not be based solely on the
automated processing of PNR data. The Commission also proclaimed that the categories of PNR
data exchanged should be as limited as possible and that PNR data should be retained no longer
than absolutely necessary. In November 2010, the European Parliament welcomed the
Commission’s PNR strategy and endorsed the opening of new PNR negotiations with the United
States. The EP emphasized, however, that the exchange of PNR data must be both “necessary”
and “proportional,” reiterated that PNR data must not be used for data mining or profiling, and
called on the Commission to also explore less intrusive alternatives.29
Although many U.S. officials had been wary about reopening negotiations on the PNR accord,
the Obama Administration assented to discussing at least some adjustments, largely in recognition
of the fact that the EP was unlikely to approve the 2007 agreement. U.S.-EU negotiations on a
revised PNR accord were launched in December 2010. U.S. officials continued to maintain that
the 2007 accord sufficiently protected both the data collected and individual privacy rights; they
noted that two joint reviews conducted by the U.S. Department of Homeland Security (DHS) and
the European Commission since 2004 confirmed that the United States had not misused the PNR
data. U.S. policymakers asserted that any revised PNR agreement must not degrade the
operational effectiveness of the current PNR program and should permit further enhancements.
U.S. officials also cautioned that any new PNR agreement with the EU must not invalidate
bilateral PNR deals that the United States had concluded with various EU member states.30 In
mid-May 2011, resolutions were introduced in the House (H.Res. 255) and passed in the Senate
(S.Res. 174) essentially supporting the existing 2007 U.S.-EU PNR accord and urging DHS to
reject any efforts by the EU to modify the agreement in a way that would degrade its usefulness
in the fight against terrorism.
In late May 2011, the United States and the European Commission concluded negotiations on a
revised PNR agreement, a draft of which was leaked to the press. According to U.S. officials, this
draft PNR accord contained new innovations to enhance the protection of passengers’ personal
information. For example, regarding the retention of PNR data, the May 2011 agreement
introduced a new provision whereby after six months, portions of a passenger’s record would be
depersonalized and “masked” (or hidden); it decreased the time that PNR data would be stored in

an “active” database; and progressively restricted the number of authorized personnel with access
to the data. U.S. officials contended that the draft accord provided greater legal certainty and
clarity on a passenger’s rights to redress, and affirmed that the United States would not make a
decision to deny boarding based solely on the automated processing of PNR data. In addition, it
recognized that should the EU in the future develop its own PNR system, the parties would
consult to determine if it necessitated making any changes to the existing accord in order to
ensure full reciprocity between the two systems.31
Despite these revisions to the U.S.-EU PNR agreement, press reports indicated that some MEPs
remained unsatisfied. They pointed out that the May 2011 version of the accord still allowed the
United States to retain passenger data ultimately for up to 15 years (albeit in a “dormant” state
after 5 years), did not reduce the amount of data transferred (the 19 categories remained the same
as in the 2007 agreement), and increased the requirement that airlines transmit the data to U.S.
authorities from 72 hours before a flight departs to at least 96 hours. Furthermore, some MEPs
worried that the new deal broadened the use of PNR data to more criminal offenses than
contained in the 2007 iteration.32
In October 2011, the House Homeland Security Committee’s Subcommittee on Counterterrorism
and Intelligence held a hearing on intelligence-sharing and terrorist travel, at which the
negotiations on the U.S.-EU PNR agreement figured prominently. U.S. officials testifying at the
hearing asserted that the May 2011 draft of the PNR accord was stronger than the 2007 version,
preserving and in some cases improving its operational effectiveness. At the same time, they
noted, it addressed all concerns raised by the EU, including those pertaining to data security and
protection, the scope of offenses covered, and the right of passengers to redress.33
Nevertheless, in an effort to further assuage European concerns, U.S. and EU negotiators
continued to work on revising the PNR accord. In November 2011, the United States and the EU
concluded a new draft PNR agreement, which the European Commission asserted contained “real
improvements” over the version leaked in May. Although the November 2011 iteration was
similar to the May 2011 version and retained many of its same provisions, two further changes
were included that were aimed at meeting EU demands: limiting the use of PNR data specifically
to terrorist or other serious transnational crimes that could result in three years or more in prison;
and varying the retention time depending on the type of crime under investigation (data would

31 Although the European Commission first floated establishing an EU PNR system in November 2007, progress has
been slow because of different member state sensitivities about privacy rights and counterterrorism practices. In
February 2011, the Commission presented a new proposal for an EU-wide PNR system. In April 2012, EU member
states approved creating an EU PNR system that would oblige airlines to transfer the PNR data of passengers on
international flights into and out of EU territory to the member state of arrival or departure; member states would be
allowed to collect PNR data from intra-European flights but not required to do so (mandating the inclusion of PNR data
from intra-European flights was controversial for some EU members because of data privacy concerns). The European
Parliament, however, must still approve establishing this EU PNR system, but some MEPs have opposed certain
elements of the current proposal. In April 2013, it was rejected by a key parliamentary committee; at present, it is
unclear whether the existing proposal will be put to a full plenary vote. “PNR-EU27 Outline European System,”

still be retained ultimately for 15 years for terrorist investigations, but only 10 years for
investigations into other types of crimes).34
In December 2011, EU member states approved the new U.S.-EU PNR agreement, although
Germany and Austria abstained because they still viewed the data retention and redress provisions
in the new accord as insufficient. Some MEPs shared these concerns, maintaining that the
additional changes in the November 2011 PNR accord were largely cosmetic and that it should
therefore be rejected. Other MEPs backed the new agreement, noting European Commission
arguments that the accord contained stronger data protection guarantees than the 2007 version. A
number of MEPs asserted they would vote for the 2011 accord despite some misgivings regarding
the data privacy safeguards because in their view, it was better to have an agreement providing
the airlines with legal certainty than no agreement at all (the Commission contended that should
the Parliament reject this latest version of the PNR agreement, the United States had made clear
there would be no further negotiations).35
On March 27, 2012, the European Parliament’s Civil Liberties Committee endorsed the
November 2011 U.S.-EU PNR agreement by a vote of 31 to 23. On April 19, 2012, the full
Parliament approved the PNR accord by a vote of 409 to 226, with 33 abstentions. The United
States has welcomed the Parliament’s endorsement of the PNR accord; U.S. officials assert that it
reaffirms the shared commitment of the United States and the EU to countering terrorism and
other transnational threats while protecting privacy and other civil rights. The new U.S.-EU PNR
agreement took effect on June 1, 2012, and will be valid until 2019.36
U.S.-EU Data Privacy and Protection Agreement
Many U.S. and EU leaders believe that law enforcement information-sharing agreements such as
SWIFT and PNR are vital tools in the fight against terrorism. At the same time, U.S. officials
have often been frustrated by the need for painstaking and often time-consuming negotiations
with the EU on every individual agreement that involves sharing personal data between the two
sides. For many years, Washington has sought to establish an umbrella agreement in which the
EU would largely accept U.S. data privacy standards as adequate and thus make the negotiation
of future data-sharing accords easier in the law enforcement arena. In the past, EU officials had
largely resisted this idea, claiming that only tailored agreements could guarantee an “added level
of protection” for EU citizens against possible U.S. infringements of their privacy rights.
In 2009, the European Parliament called for a U.S.-EU framework agreement to help better
ensure the protection of personal data exchanged between the two sides in the fight against
terrorism and crime. In late May 2010, the European Commission proposed a draft mandate for
negotiating such an accord that could apply to all U.S.-EU data-sharing agreements in the law
enforcement context. The Commission hopes that an overarching deal on data protection will

bridge what it views as U.S.-EU differences in the application of privacy rights and guarantee that
all data transferred is subject to high standards of protection on both sides of the Atlantic. The
Commission noted, however, that any such framework agreement would not provide the legal
basis for the actual transfer of personal data between the EU and the United States, and that
specific agreements on SWIFT or PNR, for example, would still be required.37 EU member states
approved the Commission’s mandate in early December 2010.
In March 2011, the United States and the EU officially launched negotiations on a framework
Data Privacy and Protection Agreement (DPPA) to protect personal information exchanged in a
law enforcement context. U.S. officials assert that this U.S.-EU accord should be based broadly
on the principle of mutual recognition of each other’s data protection systems, thus making it
clear that while the U.S. and EU regimes may differ, they both protect citizens’ rights to privacy
and other civil liberties effectively. As such, U.S. authorities hope that the negotiations will
ultimately result in an EU finding of “adequacy” for U.S. data protection standards. Many
analysts believe that the DPPA will likely build on the common personal data protection
principles adopted by the United States and the EU in October 2009.38
U.S. and EU officials assert that considerable progress has been made in negotiating a DPPA,
including on provisions related to data security, the transparency of data processing, maintaining
the quality and integrity of information, and oversight. However, some controversial issues
remain, including purpose limitation, retention times, and redress. Many EU officials and MEPs
insist that European citizens need the right of judicial redress in the United States; some experts
believe that the EU will likely push for the U.S. Privacy Act of 1974 to be amended to extend
judicial redress to EU citizens (currently, the U.S. Privacy Act limits judicial redress to U.S.
citizens and legal permanent residents). U.S. experts doubt that the Obama Administration would
agree to this potential EU demand, given that Congress would probably not be inclined to pass
such an amendment to the Privacy Act. The Administration has long maintained that EU citizens
may seek redress concerning U.S. government handling of personal information through agency
administrative redress or judicial redress through other U.S. laws, such as the U.S. Freedom of
Information Act. Another possible point of contention in U.S.-EU negotiations may be whether or
not the DPPA should be applied retroactively to previous U.S.-EU data sharing arrangements.
Some EU leaders and MEPs support its retroactive application, but the United States argues that it
would create unnecessary legal uncertainty.39
Amid such stumbling blocks, many observers suggest that the DPPA negotiations appear largely
stalled. Some commentators believe that the recent revelations of U.S. surveillance activities may
inject greater momentum into the DPPA discussions. In the European Parliament’s previously
noted July 2013 resolution on the NSA programs, MEPs called for the European Commission and
U.S. authorities to resume the negotiations on a DPPA “without delay.”40 EU officials and many
MEPs hope that the United States may now be more willing to meet certain EU demands,
especially on the issue of redress, in part to restore trust and confidence in U.S. data protection

commitments. However, other experts contend that the NSA activities may prompt EU
negotiators to take an even tougher stance in the DPPA talks, thus making it more difficult to find
common ground. EU member states and the European Parliament must ultimately approve any
eventual U.S.-EU DPPA for it to take effect.41
Strengthening Border Controls and Transport Security
According to the U.S. Department of Homeland Security, roughly 30,000 passengers arrive daily
from Europe at U.S. ports of entry, as do more than 3,000 commercial containers.42 Over the last
decade, the United States and the EU have emphasized cooperation in the areas of border control
and aviation and maritime security, and have concluded several agreements on such issues. The
two sides have sought to enhance international information exchanges on lost and stolen
passports and to promote the use of interoperable biometric identifiers to enhance travel
document security. In January 2010, the United States and the EU issued a joint declaration in
which they pledged to intensify U.S.-EU efforts to strengthen aviation security measures
worldwide, and in October 2010, U.S.-EU collaboration played a key role in forging an
International Civil Aviation Organization (ICAO) declaration on aviation security, agreed to by
190 countries. Recently, the United States and the EU have placed considerable emphasis on
improving cargo security and strengthening global supply chain security. In a joint statement in
June 2011, the United States and the EU reaffirmed their determination to bolster supply chain
security and foster greater global cooperation on this issue. At the same time, U.S. and EU
officials continue to grapple with finding the appropriate balance between improving border
security and facilitating legitimate transatlantic travel and commerce.
Aviation and Air Cargo Security
Since the 2001 terrorist attacks in which airplanes were used as weapons, both the United States
and the EU have implemented a range of measures aimed at improving aviation security.43
Several incidents over the last few years have brought aviation and air cargo security to the
forefront of U.S.-EU discussions again, especially the December 2009 attempt by a Nigerian
passenger to blow up an airliner en route from Amsterdam to Detroit with a device concealed in
his underwear; and the thwarted October 2010 “Yemen bomb plot,” in which two Chicago-bound
printer cartridge packages containing explosives were shipped from Yemen on various cargo and
passenger flights (one package was transferred in Germany before being intercepted in the UK).
The discovery in May 2012 of a plot to down a civilian aircraft using a device similar to the one
used in the December 2009 attempt highlights the continuing terrorist threat to aviation.
Many U.S. and EU rules and regulations implemented since 2001 have coincided closely, and the
two sides have sought to work together to bridge gaps in their respective policies given the

and updated in 2008 and became fully applicable in April 2010.

significant volume of transatlantic flights (more than 2,500 every week). For example, in 2003,
some EU countries objected to new U.S. rules requiring armed air marshals on certain flights to
and from the United States; U.S. officials pledged to consider alternative measures for European
countries opposed to armed air marshals. Moreover, in 2008, the United States and the EU
reached an agreement on coordinating air cargo security measures.44 Among other provisions, the
two sides pledged to institute commensurate systems to ensure the security of all cargo on
passenger flights between their respective territories, in part to comply with a provision in the
Implementing Recommendations of the 9/11 Commission Act of 2007 (P.L. 110-53) that
mandates 100% screening of cargo transported on U.S. domestic and U.S.-bound international
passenger flights equivalent to the level of security used for checked baggage.45
In June 2012, the United States and the EU announced that they had reached an agreement on an
air cargo security partnership, in which each side will recognize the other’s air cargo security
regime, thereby eliminating duplication of security controls and the need to implement different
regimes depending on the destination of air cargo. U.S. and EU officials assert that this mutual
recognition of air cargo security regimes will enhance cargo security and result in huge savings
for U.S. and European cargo operators in terms of both time and money, improving the speed of
transatlantic shipments and reducing costs. As part of the agreement, both sides also pledged to
exchange information on the evolution and the implementation of their security regimes.
According to press reports, EU officials assert that this mutual recognition agreement will enable
European operators to meet the U.S. requirement for 100% screening of cargo on passenger
planes bound for the United States from abroad contained in the Implementing Recommendations
of the 9/11 Commission Act of 2007, noted above.46
Despite a shared commitment to promote U.S.-EU cooperation in the areas of aviation and air
cargo security, some differences in perspective remain. In the aftermath of the failed 2009 attack,
the United States accelerated installation of body scanners at U.S. airports and encouraged the EU
to follow suit. Although some EU countries and leaders supported installing body scanners at
European airports, other EU member states were hesitant due to concerns that the scanners could
compromise privacy rights and pose health dangers. Some Members of the European Parliament
expressed similar worries. However, in July 2011, the European Parliament backed the use of
body scanners at EU airports provided that safeguards were instituted to protect passenger
privacy and ensure passenger health; the safeguards recommended by the EP included the
requirement that scans only produce stick figure images and not body images, and a ban on x-ray
scans (an alternative millimeter wave scan was permitted instead). The EP also asserted that the
use of the scanners should be voluntary, with passengers having the right to opt for a manual
search. In November 2011, the European Commission adopted the EP’s conditions in setting

45 In the United States, the screening of all cargo on passenger flights, as called for in P.L. 110-53, has been
implemented in stages. The U.S. Transportation Security Administration (TSA) has required the screening of all cargo
transported on U.S. domestic passenger flights since August 2010, and the screening of all cargo on international
passenger flights inbound to the United States since December 2012. For more information, see CRS Report R41515,

common standards for the use of body scanners at EU airports. However, member states are not
required to deploy such scanners and some are unlikely to do so.47
Some EU officials and European Parliamentarians have also been uneasy about the use of body
scanners at U.S. airports, given the large volume of European visitors to the United States.
However, at least some European privacy and health worries were likely assuaged in January
2013, when the U.S. Transportation Security Administration (TSA) announced that it would
remove all full-body scanners that produce detailed, revealing images by June 2013. Body
scanners will remain at U.S. airports, but only those that produce more generic body images will
be employed and most (but not all) of these scanners (either currently in use or contracted for by
the TSA) use millimeter wave technology rather than low-dose x-rays. Many Members of
Congress, like their counterparts in the European Parliament, had long expressed concerns that
the more revealing body scanners violated passengers’ privacy rights.48
Meanwhile, U.S. officials have been worried about planned changes to EU regulations governing
liquids and gels in carry-on baggage on board planes. Following the August 2006 disruption of a
plot to use liquid explosives to blow up transatlantic flights, the United States and the EU began
prohibiting passengers from carrying most liquids and gels on board planes. The United States
has worked with the EU and other countries to harmonize the small amounts of travel-sized
liquids and gels that are permitted in carry-on baggage in an effort to minimize inconvenience to
international travelers. In 2010, however, the EU announced plans to eliminate restrictions on
liquids in cabin baggage by April 2013, following the introduction of liquid screening equipment
in all EU airports. U.S. policymakers voiced concerns about the effectiveness of current liquid-
screening technology and argued that it was premature to ease the liquid and gel restrictions.
Some EU governments and segments of the airline industry expressed similar worries about
airline security and noted that the planned changes could result in potential flight delays.
In light of these various concerns, the EU has postponed the original 2013 deadline for
introducing liquid screening equipment and eliminating all restrictions on liquids and gels in
carry-on baggage. The EU maintains that it is still committed to removing such restrictions in the
longer term, but acknowledges that the extent of the change could present “operational risks.”
Instead, the European Commission has proposed that EU restrictions on “duty-free” liquids and
gels in cabin baggage be lifted by January 2014, and that subsequent phases aimed at removing
all restrictions on liquids in carry-on baggage will be announced at the “earliest possible date.”49

47 For example, the UK, the Netherlands, France, and Italy have been trying out full-body scanners at their airports, but
Germany, Spain, and some Nordic countries remain more cautious about using the scanners. “EU Puts Off Reply To

U.S.-EU Cooperation Against Terrorism

Maritime Cargo Screening
In April 2004, the United States and the European Union signed a customs cooperation accord;
among other measures, it calls for extending the U.S. Container Security Initiative (CSI)
throughout the EU. CSI stations U.S. customs officers in foreign ports to help pre-screen U.S.-
bound maritime cargo containers to ensure that they do not contain dangerous substances such as
explosives or other weapons of mass destruction. Ten EU member states currently have ports that
participate in CSI.
In May 2012, the United States and the EU agreed to recognize each other’s trusted shipper
programs in an effort to improve supply chain security and boost trade opportunities. This mutual
recognition accord is intended to speed up customs procedures for some 15,000 U.S. and
European companies designated as “trusted traders” by either the U.S. Customs-Trade Partnership
Against Terrorism (C-TPAT) program or the EU’s Authorized Economic Operators (AEO)
regime. U.S. and EU officials hope this agreement will not only lower costs and simplify
procedures for trusted traders but also allow customs authorities to concentrate limited resources
on risky consignments and better facilitate legitimate transatlantic trade.
Recently, U.S.-EU tensions have receded over a provision in the Implementing Recommendations
of the 9/11 Commission Act of 2007 (P.L. 110-53) that set a five-year goal of scanning at foreign
ports of loading all containers bound for the United States for nuclear devices. Although
European leaders supported the use of radiation detection and container imaging to increase cargo
and freight security in principle, they viewed 100% container scanning as unrealistic, and argued
that it could disrupt trade and place a heavy financial burden on EU ports and businesses. U.S.
officials in both the Bush and Obama Administrations shared these concerns about the cost and
effectiveness of 100% scanning, suggesting that it could result in lower profits and higher
transportation costs for U.S. importers; they also pointed out that the United States and Europe
already had programs in place to identify high risk cargo shipments and target them for further
inspection. In May 2012, the U.S. Department of Homeland Security notified Congress that it was
extending the July 2012 100% scanning deadline by two years. Proponents of 100% scanning
continue to urge its full implementation, arguing that the manifest data currently used by U.S. and
European authorities to determine which containers need closer scrutiny is not an adequate basis
for determining risk.50
Visa Waiver Program (VWP)
For many years, the United States and the EU were at odds over the U.S. Visa Waiver Program
(VWP) and the EU’s desire to have it applied equally to all EU members. The VWP allows for
short-term visa-free travel for business or pleasure to the United States from 37 countries, most of
which are in Europe. New EU members were eager to join the VWP, but most were excluded for
years due to problems meeting the program’s statutory requirements. Although some Members of
Congress had long expressed skepticism about the VWP in general because of security concerns
(noting that terrorists with European citizenship have entered the United States on the VWP),
other Members were more supportive of extending the VWP to new EU members (especially

those in central and eastern Europe) given their roles as U.S. allies in NATO and in the fight
against terrorism.
In July 2007, Congress passed the Implementing Recommendations of the 9/11 Commission Act
of 2007 (P.L. 110-53), which included changes to the VWP aimed at both strengthening the
program’s security components and allowing more EU members (and other interested countries)
to qualify. Among other measures, P.L. 110-53 called on VWP participants to meet certain
security and passport standards and to sign on to a number of information-sharing agreements; at
the same time, it eased other admission requirements to make it easier for some EU member
states to join the VWP. As a result, 23 of the EU’s 28 member states now belong to the VWP. The
EU, however, continues to encourage the United States to admit the remaining five EU members
(Bulgaria, Croatia, Cyprus, Poland, and Romania) to the VWP as soon as possible.
Some European policymakers also remain irritated by new rules requiring visitors entering the
United States under the VWP to submit biographical information to U.S. authorities through the
web-based Electronic System for Travel Authorization (ESTA) at least two days before traveling.
The creation of ESTA was mandated by Congress in P.L. 110-53 as one way to help increase the
security of the VWP; ESTA became operational for all VWP countries in January 2009. ESTA
checks the biographical information submitted against relevant law enforcement databases; those
individuals not approved under ESTA must obtain a U.S. visa. Some EU officials contend that
ESTA essentially comprises a new type of visa requirement, is a hardship for some last-minute
business travelers, and infringes on EU privacy and data protection rules; many European
policymakers and citizens also bristle at the $14 fee for ESTA processing imposed since
September 2010. U.S. authorities counter that ESTA only requires the same information as that
required on the current I-94W paper form that VWP visitors must complete en route to the United
States, and that ESTA approval is good for two years and valid for multiple entries.51
Detainee Issues and Civil Liberties
U.S. and European officials alike maintain that the imperative to provide freedom and security at
home should not come at the cost of sacrificing core principles with respect to civil liberties and
upholding common standards on human rights. Nevertheless, the status and treatment of
suspected terrorist detainees has often been a key point of U.S.-European tension. Especially
during the former George W. Bush Administration, a number of U.S. policies were subject to
widespread criticism in Europe; these included the U.S.-run detention facility at Guantánamo
Bay, Cuba; U.S. plans to try enemy combatants before military commissions; and the use of
“enhanced interrogation techniques.” The U.S. practice of “extraordinary rendition” (or
extrajudicial transfer of individuals from one country to another, often for the purpose of
interrogation) and the possible presence of CIA detention facilities in Europe also gripped
European media attention and prompted numerous investigations by the European Parliament,
national legislatures, and judicial bodies, among others. Some individuals held at Guantánamo
and/or allegedly subject to U.S. rendition have been European citizens or residents.
Many European leaders and analysts viewed these U.S. terrorist detainee and interrogation
policies as being in breach of international and European law, and as degrading shared values
regarding human rights and the treatment of prisoners. Moreover, they feared that such U.S.

U.S.-EU Cooperation Against Terrorism

policies weakened U.S. and European efforts to win the battle for Muslim “hearts and minds,”
considered by many to be a crucial element in countering terrorism. The Bush Administration,
however, defended its detainee and rendition polices as important tools in the fight against
terrorism, and vehemently denied allegations that such policies violated U.S. human rights
commitments. Bush Administration officials acknowledged European concerns about
Guantánamo and sought agreements with foreign governments to accept some Guantánamo
detainees, but maintained that certain prisoners were too dangerous to be released.
U.S.-EU frictions over terrorist detainee policies have subsided to some degree since the start of
the Obama Administration. EU and other European officials welcomed President Obama’s
announcement in January 2009 that the United States intended to close the detention facility at
Guantánamo within a year. They were also pleased with President Obama’s executive order
banning torture and his initiative to review Bush Administration legal opinions regarding
detention and interrogation methods. In March 2009, the U.S. State Department appointed a
special envoy to work on closing the detention facility, tasked in particular with persuading
countries in Europe and elsewhere to accept detainees cleared for release but who could not be
repatriated to their country of origin for fear of torture or execution. Some EU members accepted
small numbers of released detainees, but others declined.
At the same time, the Obama Administration has faced significant challenges in its efforts to close
Guantánamo. Some observers contend that U.S. officials have been frustrated by the reluctance of
other countries, including some in Europe, to take in more detainees. Congressional opposition to
elements of the Administration’s plan for closing Guantánamo, and certain restrictions imposed
by Congress (including on the Administration’s ability to transfer detainees to other countries
amid concerns that some released detainees were engaging in terrorist activity), have also
presented obstacles. Consequently, the Obama Administration has not fulfilled its promise to shut
down Guantánamo. In March 2011, President Obama signed an executive order that in effect
creates a formal system of indefinite detention for those detainees at Guantánamo not charged or
convicted but deemed too dangerous to free. The Administration also announced in March 2011
an end to its two-year freeze on new military commission trials for Guantánamo detainees.52
Some European policymakers continue to worry that as long as Guantánamo remains open, it
helps serve as a recruiting tool for Al Qaeda and its affiliates. Some European officials have also
voiced concern about those detainees at Guantánamo who began hunger strikes in early 2013 to
protest their ongoing incarceration. In May 2013, the European Parliament adopted a resolution
that expresses concern for those on hunger strike, and again calls upon the United States to close
the detention facility.53
The Obama Administration asserts that it is still committed to closing Guantánamo. In late May
2013, President Obama renewed his pledge to work toward this goal; as a first step, he announced
that U.S. authorities would restart the process of sending home or resettling in third countries
those detainees already cleared for transfer. In August 2013, the Administration released two
Algerian detainees (the first such releases in nearly a year), after certifying to Congress that they

no longer posed a threat to U.S. national security. Press reports indicate that 164 detainees
currently remain at Guantánamo.54
European concerns also linger about the past role of European governments in U.S. terrorist
detainee policies and practices. In September 2012, the European Parliament passed a non-
binding resolution (by 568 votes to 34, with 77 abstentions) calling upon EU member states to
investigate whether CIA detention facilities had existed on their territories.55 The resolution urged
Lithuania, Poland, and Romania in particular to open or resume independent investigations, and
called on several other member states to fully disclose all relevant information related to
suspected CIA flights on their territory. Meanwhile, some U.S. and European officials worry that
allegations of U.S. wrongdoing and rendition-related criminal proceedings against CIA officers in
some EU states (stemming from the Bush era) continue to cast a long shadow and could put vital
U.S.-European intelligence cooperation against terrorism at risk.56
U.S. Perspectives and Issues for Congress
Successive U.S. administrations and many Members of Congress have supported efforts to
enhance U.S.-EU cooperation against terrorism since the 2001 terrorist attacks. Although some
skeptics initially worried that such U.S.-EU collaboration could weaken strong U.S. bilateral law
enforcement relationships with EU member states, the George W. Bush Administration essentially
determined that the political benefits of engaging the EU as an entity on police and judicial
matters outweighed the potential risks given Europe’s role as a key U.S. law enforcement partner.
They also hoped that improved U.S.-EU cooperation on border controls and transport security
would help authorities on both sides keep better track of suspected terrorists and prevent them
from entering the United States or finding sanctuary in Europe.
At the same time, some observers note that U.S.-EU counterterrorism cooperation is complicated
by different EU and member state competencies, and U.S. policy preferences. An increasing
number of policy areas relevant to counterterrorism—including data protection, customs, and
visas—fall under the competence of the Union (i.e., EU members adopt a common policy, agree
to abide by its terms, and negotiate collectively with other countries). However, at times, the
United States continues to prefer to negotiate on some issues—such as the VWP—bilaterally, and
observers assert that this disconnect can lead to frictions in the U.S.-EU relationship.
Nevertheless, both the United States and the EU appear committed to fostering closer cooperation
in the areas of counterterrorism, law enforcement, border controls, and transport security. As
noted above, the Obama Administration has largely continued the Bush Administration’s policy
of engagement with the EU in these areas. Congressional decisions related to improving U.S.
travel security and border controls, in particular, may affect how future U.S.-EU cooperation
evolves. Data privacy, aviation and cargo security, and visa policy will continue to be salient
issues for Congress in this respect.

U.S.-EU Cooperation Against Terrorism

In addition, given the European Parliament’s growing influence in many of the areas related to
counterterrorism and its new role in approving international agreements—such as the U.S.-EU
SWIFT and PNR accords—Members of Congress may increasingly be able to help shape
Parliament’s views and responses. Some Members of Congress have ongoing contacts with their
counterparts in the Parliament, and the existing Transatlantic Legislators’ Dialogue (TLD) brings
members of the European Parliament and the U.S. House of Representatives together twice a year
to discuss a wide range of topical political and economic issues. Some Members of Congress and
European Parliamentarians have recently expressed interest in strengthening ties and cooperation
further. Such exchanges could provide useful opportunities for enhancing transatlantic dialogue
on the wide range of counterterrorism issues facing both sides of the Atlantic.57
