U.S.-EU Cooperation Against Terrorism

Summary
The September 11, 2001, terrorist attacks gave new momentum to European Union (EU)
initiatives to combat terrorism and improve police, judicial, and intelligence cooperation among
its member states. 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 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 improve its counterterrorism capabilities, the EU has also made improving
cooperation with the United States a top priority. Washington has largely welcomed these efforts,
recognizing that they may help root out terrorist cells 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 clamp
down on terrorist financing and to improve aviation and transport security.
Despite U.S.-EU strides to foster closer counterterrorism and law enforcement cooperation, some
challenges remain. Data privacy has been and continues to be a key sticking point. In February
2010, the European Parliament rejected a U.S.-EU agreement—known as the SWIFT accord—
that would have continued allowing U.S. authorities access to financial data stored in Europe to
help combat terrorism on the grounds that it did not contain sufficient protections to safeguard the
personal data and privacy rights of EU citizens. For years, and for similar reasons, some Members
of the European Parliament have also challenged a U.S.-EU agreement permitting airlines to
share passenger name record (PNR) data with U.S. authorities. Although the European Parliament
approved a revised U.S.-EU SWIFT agreement in July 2010, some observers worry that the
Parliament may also initially reject the most recent U.S.-EU PNR agreement. Other points of
U.S.-EU tension include issues related to balancing border security with legitimate transatlantic
travel and commerce and terrorist detainee policies.
Nevertheless, both the United States and the EU appear committed to fostering closer cooperation
in the areas of counterterrorism and other homeland security issues. 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 111th Congress. For additional background, also

U.S.-EU Cooperation Against Terrorism

Background on European Union (EU) 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 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 27 member states.1 The EU
has long sought to harmonize policies among its members in the area of “justice and home
affairs” (or JHA) as part of the Union’s drive toward further integration. 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 other 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—especially in areas such as police
and judicial cooperation and counterterrorism—were hampered by member state concerns that
doing so could infringe on their national legal systems and sovereignty. Insufficient resources and
a lack of trust among national 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.

1 The 27 members of the EU are: Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom. For more information on the EU, its
institutions, and policies, see CRS Report RS21372, The European Union: Questions and Answers, by Kristin Archick

U.S.-EU Cooperation Against Terrorism

The March 2004 terrorist bombings in Madrid injected a greater sense of urgency into EU
counterterrorism efforts, and gave added impetus to EU initiatives aimed at improving travel
document security and impeding terrorist travel. In the wake of the Madrid attacks, the EU also
created a new 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.
The July 2005 terrorist attacks on London’s mass transport system prompted additional EU
efforts to improve police, judicial, and intelligence cooperation. In December 2005, the EU
adopted a new counterterrorism strategy outlining EU goals to prevent, protect, pursue, and
respond to the international terrorist threat. The EU also set out a plan to combat radicalization
and terrorist recruitment. Following the disruption of a plot to use liquid explosives to blow up
airliners flying from the UK to the United States in August 2006, the EU agreed on a package of
new measures to further improve and harmonize air security among its member states; these new
rules included prohibiting passengers from carrying most liquids on board planes.2 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 working to improve the security of
explosives and considering the development of an EU-wide system for the exchange of airline
passenger data.
Most observers view the EU has 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
27 member states. However, the EU’s new 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 the EU will likely still seek consensus as much as possible on
sensitive JHA policies, such as those related to countering terrorism.3
Despite the political commitment of EU leaders to promote cooperation in the JHA field and
improve its collective ability to better combat terrorism, the EU’s drive to forge common internal
security policies still faces several hurdles. Implementation of EU policies in the JHA field is up
to the member states and as noted above, considerable lag times often exist between when an
agreement is reached in Brussels and when it is implemented at the national level. For example,

2 The EU first adopted common rules on aviation security in 2002, detailing measures regarding access to sensitive
airport areas, aircraft security, passenger screening and baggage handling, among others. In April 2010, the EU revised
its aviation security measures and plans to eliminate the prohibition on liquids in cabin baggage by 2013, following the
introduction of liquid screening equipment in all EU airports. “EU To Ease Air Curbs Aimed at Liquid Explosives,”
Reuters, April 29, 1010.
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
information on the Lisbon Treaty, see CRS Report RS21618, The European Union’s Reform Process: The Lisbon
Treaty

U.S.-EU Cooperation Against Terrorism

several EU members did not meet the initial 2004 deadline for transposing the EU arrest warrant
into national law due to civil liberty and data privacy concerns. 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. As a result
of these and other ongoing challenges, 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

As part of the EU’s efforts to combat terrorism since September 11, 2001, the EU made
improving law enforcement cooperation with the United States a top priority. The previous 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
and highlighting the commitment of both sides to combat terrorism within the rule of law.
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

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.

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. In
2010, U.S. and EU officials began 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 November 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
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 April 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 February 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

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 2010.

U.S.-EU Cooperation Against Terrorism

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.
Stemming Terrorist Financing
The United States and the EU have been active partners in efforts to 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. U.S. and EU officials have also worked to bridge gaps
in their respective lists of individuals and groups that engage in terrorist activities. The United
States views doing so as important not only for its symbolic value, but also because of the asset-
freezing requirements that the EU attaches to those on its list.
The United States and the EU also 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. U.S. authorities have shared
over 1,550 leads resulting from the SWIFT data with European governments and many of these
leads have helped in the prevention or investigation of terrorist attacks in Europe.7 However, in
February 2010, U.S. access to much of the SWIFT data was essentially suspended following a
vote by the European Parliament (a key EU institution) to reject a 2009 U.S.-EU SWIFT
agreement on data privacy and civil liberty grounds. In late June 2010, the United States and the
EU revised the U.S.-EU SWIFT accord to meet Parliament’s concerns and thereby allow U.S.
authorities continued access to SWIFT data. The European Parliament approved this latest
iteration of the accord on July 8, 2010. (For more information on the U.S.-EU SWIFT agreement,
see “Tracking Terrorist Financing” in “Ongoing Challenges,” below).

U.S.-EU Cooperation Against Terrorism

Border Control and Transport Security
The United States and the EU have also emphasized cooperation in the areas of border control
and transport security, as seen by the creation of the high-level policy dialogue on these issues.
The United States and the EU have pledged to enhance international information exchanges on
lost and stolen passports and to promote travel document security through the use of interoperable
biometric identifiers. Several agreements related to border controls and transport security have
also been concluded.
Container Security Initiative (CSI)
In April 2004, the United States and EU signed a customs cooperation accord; among other
measures, it calls for extending the U.S. Container Security Initiative (CSI) throughout the Union.
CSI stations U.S. customs officers in foreign ports to help pre-screen U.S.-bound cargo containers
to ensure that they do not contain dangerous substances such as weapons of mass destruction. Ten
EU member states currently have ports that participate in CSI. Both the United States and the EU
have also instituted programs with leading importers to pre-screen cargo shipments.
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.
This accord was controversial in Europe because of fears that it compromised EU citizens’ data
privacy rights. 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 EU citizens’ 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 U.S. Customs and Border Protection to
share PNR data with other U.S. agencies engaged in the fight against terrorism; extending the
length of time that the United States can store such data; 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 requires airlines to send data from their
reservation systems to U.S. authorities at least 72 hours before a flight departs. Although this
U.S.-EU PNR agreement has been provisionally in force since 2007, the European Parliament
must still give its approval in order for this accord to be formally signed and remain in force (see
“Sharing Airline Passenger Data” in “Ongoing Challenges,” for more information).8
Aviation Security
For many years, the United States and the EU have also worked together on measures to improve
aviation security. This issue came to the forefront of U.S.-EU discussions again following the

Transfer of Air Passenger Details,” Agence Europe, March 6, 2010.

U.S.-EU Cooperation Against Terrorism

December 2009 attempt by a Nigerian to blow up an airliner en route from Amsterdam to Detroit.
In January 2010, the United States and the EU issued a joint declaration on aviation security,
pledging to enhance not only U.S.-EU cooperation further but also to intensify U.S.-EU efforts to
strengthen aviation security measures and standards worldwide. As part of this endeavor, the
United States and the EU have been discussing ways to improve security at European airports,
including by installing full-body scanners. The United States has accelerated installation of body
scanners at U.S. airports in the aftermath of the failed 2009 airline attack, and has encouraged the
EU to follow suit. Although some EU countries and leaders support installing body scanners,
other EU member states and some European Parliamentarians remain hesitant due to concerns
that the scanners could compromise privacy rights and pose health dangers.9
In addition, the United States and the EU have discussed the use of armed air marshals on
transatlantic flights. Some European countries objected to U.S. requirements issued in December
2003 for armed marshals on certain flights to and from the United States, viewing guns on board
planes as increasing the security risks. Others, such as the U.K. and France, were more receptive
to deploying armed air marshals. In April 2004, U.S. officials pledged to consider alternative
measures for European countries opposed to armed air marshals. In November 2004, U.S. and EU
officials agreed to exchange information about aviation security technologies , such as airline
countermeasures against shoulder-fired ground-to-air missiles.10
Ongoing Challenges
Despite U.S.-EU strides since 2001 to foster closer counterterrorism and law enforcement
cooperation, and a shared commitment to do so, some challenges remain. Among the most
prominent are: data privacy (especially in relation to the U.S.-EU SWIFT and PNR agreements);
balancing security and transatlantic travel and commerce; and detainee and civil liberty issues.
Differences in the U.S. and EU terrorist designation lists have also led to periodic tensions.
Data Privacy
Data privacy has been and continues to be a key U.S.-EU sticking point. As noted above, 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 many U.S.-EU agreements, from those related to Europol to PNR to SWIFT, many
EU officials have been concerned about whether the United States could guarantee a sufficient
level of protection for European citizen’s 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.

9 For example, the UK, the Netherlands, France, and Italy reportedly plan to try out full-body scanners at their airports,
while Germany, Spain, and some Nordic countries appear more cautious about using the scanners. See “EU Puts Off
Reply To U.S. Request for Airport Body Scanners,” Agence France Presse, January 21, 2010; “U.S. Aims To
Overcome Europe’s Doubts About Airport Body Scanners,” Deutsche Welle, January 21, 2010.

U.S.-EU Cooperation Against Terrorism

Tracking Terrorist Financing
Controversy over SWIFT and Europe’s role in the U.S. Terrorist Finance Tracking Program
(TFTP) surfaced originally in 2006, following press reports that U.S. authorities had been granted
secret access to SWIFT 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 U.S. and EU
reached a deal to allow continued U.S. access to SWIFT data for counterterrorism purposes, but it
remained controversial for some European politicians and privacy groups.11
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 an accord with the United States on SWIFT. However, under the
EU’s new Lisbon Treaty, the European Parliament (EP) gained the right to approve or reject
international agreements such as the SWIFT accord. As discussed previously, in February 2010,
the EP rejected this new version of the U.S.-EU SWIFT agreement by a vote of 378 to 196; 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 the transfer of SWIFT data to the United
States until their views regarding the protection of data privacy and civil liberties were taken on
board more fully.
The European Commission and U.S. authorities began negotiating a new U.S.-EU SWIFT
agreement in May 2010. Two key EP concerns related to guaranteeing judicial remedy for
European citizens in the United States for 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.12
In mid-June 2010, U.S. and EU officials concluded a new draft agreement on SWIFT. 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

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.
As part of the new SWIFT accord, the United States has pledged its support and assistance in the
event of an EU decision to develop its own TFTP. Some observers point out, however, that
member states must ultimately approve a “European TFTP” and note that achieving member state
agreement may be difficult given the likely financial costs of setting up such a system. Others
suggest that a “European TFTP” would also probably entail more intelligence-sharing among EU
member states, which some members and national intelligence services have long resisted.
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 will enter into force on August 1, 2010, for a period of
five years. If the EU decides to establish its own TFTP within this time period, the United States
and the EU will consult to determine whether the agreement needs to be adjusted accordingly.13
Sharing Airline Passenger Data
Many U.S. and European officials have also been concerned that the EP will reject the U.S.-EU
PNR agreement that has been provisionally in force since 2007. As noted above, Parliament must
still give its approval to this accord for it to be formally signed and remain in force. Press reports
indicate, however, that many MEPs recognize that rejecting the current U.S.-EU PNR agreement
would create serious legal uncertainties and practical difficulties for both travelers and air
carriers. As a result, in early May 2010, the EP postponed its vote on the 2007 PNR deal with the
United States until the European Commission presents a new “PNR package.”
The Commission’s “PNR package” will reportedly include a “global external PNR strategy” (or
“single PNR model”) setting out general requirements for EU agreements with other countries
and addressing EP concerns about the amount of PNR data transferred, the length of time such
data can be kept, and the possibility for redress by European citizens of possible data misuse. The
“PNR package” may also, consequently, propose adjustments to the EU’s existing PNR
agreement with the United States in order to meet EP demands for stronger data protections. The
EP had hoped that the Commission would present this new package in July 2010. Recent media
reports suggest, however, that the Commission’s proposal for a PNR package will not be ready
until September at the earliest. Some MEPs have expressed frustration with the delay. As with the
U.S.-EU SWIFT agreement, many observers expect that the EP will press hard for changes to the
existing U.S.-EU PNR accord to better guarantee the privacy rights of EU citizens.
The EP has also been concerned with the issue of reciprocity, that is, that much of the data
transferred in the PNR agreement flows from the EU to the United States, but not vice-versa. U.S.
officials are reportedly “open” to a proposal for a similar EU-wide airline passenger data regime,
in which the personal data of U.S. citizens flying into or out of the EU would be transmitted to
European border and custom authorities for counterterrorism purposes. However, this proposed
system would also likely be controversial in Europe. Although the European Commission first

floated establishing an EU PNR system in November 2007, EU leaders have so far been unable to
agree on a concrete proposal because of different member state sensitivities regarding data
protection, privacy rights, and counterterrorism practices. The Commission will reportedly
introduce a new proposal for an EU PNR system as part of its expected “PNR package.”14
Possible U.S.-EU Framework Agreement on Data Protection
Many U.S. and EU leaders believe that 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 which would make the transfer of personal
data between EU and U.S. law enforcement authorities easier. Until recently, 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. They
argued that it would be burdensome for EU citizens to gain redress for any wrongs committed
through the U.S. judicial system.
In 2009, however, the European Parliament called for a U.S.-EU framework agreement to help
better ensure the protection of civil liberties and personal data privacy. In late May 2010, the
European Commission proposed a draft mandate for negotiating a broad accord with the United
States on personal data protection that could apply to all U.S.-EU data-sharing agreements. Such
an accord would likely build on the common personal data protection principles adopted by the
United States and the EU in October 2009. However, the Commission asserts that any eventual
framework agreement would not provide the legal basis for specific transfers of personal data
between the EU and the United States; in other words, agreements on SWIFT or PNR would still
be required. The Commission’s mandate must be approved by the member states before
negotiations with the United States can begin. Some analysts suggest that the Commission’s
proposal for a framework agreement with the United States is being driven, in part, by the recent
difficulties in securing EP support for the SWIFT and PNR deals. Although any such broad U.S.-
EU deal would also need EP approval, the Commission likely hopes that it would put EP
concerns about data privacy and U.S. protection standards to rest once and for all.15
Balancing Transatlantic Travel, Commerce, and Security
With respect to several issues, U.S. and EU officials have been grappling with finding a balance
between improving border security and facilitating legitimate transatlantic travel and commerce.

U.S.-EU Cooperation Against Terrorism

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 36 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 states) 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.16 As a result, 23 of the EU’s 27 member states now belong to the VWP, and U.S.-EU
tensions over the VWP have subsided considerably. The EU, however, continues to encourage the
United States to admit the remaining four EU members (Bulgaria, Cyprus, Poland, and Romania)
to the VWP as soon as possible.
Cargo Screening
EU officials also remain concerned with a separate provision in P.L. 110-53 that sets a five-year
goal of scanning all container ships bound for the United States for nuclear devices. Although
European leaders support the use of radiation detection and container imaging to increase cargo
and freight security in principle, they view “100 percent” scanning as unrealistic, and argue that it
could disrupt trade and would place a heavy financial burden on EU ports and businesses. Some
U.S. officials share these concerns about the cost and effectiveness of “100 percent” scanning,
suggesting that it could result in lower profits and higher transportation costs for U.S. importers;
they also point out that the United States and Europe already have programs in place to identify
“high risk” cargo shipments and target them for further inspection. Proponents of “100 percent”
scanning counter that the manifest data that U.S. and European authorities currently rely upon to
determine which containers need closer scrutiny is not an adequate basis for determining risk.17
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 and commitments on human rights. At the same time, the status and
treatment of suspected terrorist detainees has been a key point of U.S.-European tension.

U.S.-EU Cooperation Against Terrorism

Especially during the former Bush Administration, 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” came under widespread criticism in Europe. 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.
Many European leaders and analysts viewed U.S. terrorist detainee, interrogation, and
“extraordinary rendition” 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. policies weakened U.S. and EU 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
combating terrorism, and vehemently denied allegations of violating U.S. human rights
commitments, including the prohibition against torture. Bush Administration officials also
acknowledged European concerns about Guantánamo and sought agreements with foreign
governments to accept some Guantánamo detainees, but maintained that some prisoners were too
dangerous to be released.
U.S.-EU tensions over terrorist detainee policies and practices have subsided to some degree
since the advent of the Obama Administration. EU and other European officials welcomed
President Obama’s announcement in January 2009 that the United States intended to close
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.
At the same time, the Obama Administration has faced significant challenges in its efforts to close
Guantánamo. Although the one-year deadline has not been met, U.S. officials assert that they
remain committed to closing the facility as soon as possible. In March 2009, the U.S. State
Department appointed a special envoy tasked with persuading countries in Europe and elsewhere
to accept detainees cleared for release but who can not be repatriated to their country of origin for
fear of torture or execution. Although some EU members have accepted (or pledged to accept)
small numbers of released detainees, others have declined. Some observers contend that U.S.
officials are frustrated with European reluctance to take in more detainees. Some U.S. officials
also worry that allegations of U.S. wrongdoing and rendition-related criminal proceedings against
CIA officers in some EU states (stemming from the Bush era) may put vital U.S.-European
intelligence cooperation against terrorism at risk.18
Differences in the U.S. and EU Terrorist Lists
As discussed previously, the United States and the EU have sought to bring their respective
terrorist designation lists closer together in order to present a united front against these groups
and to impede terrorist financing. Some differences, however, still persist. Most notably, some EU
members continue to resist U.S. entreaties to add the Lebanon-based Hezbollah to the EU’s
common terrorist list. The United States lists Hezbollah, which is backed by Syria and Iran, as a

U.S.-EU Cooperation Against Terrorism

Foreign Terrorist Organization and applies financial and other sanctions to the group and its
members. Putting Hezbollah on the EU list would oblige EU member states to freeze the group’s
assets and block financing to the group. Those EU members opposed to including Hezbollah on
the EU’s common terrorist list argue that doing so would be counterproductive to managing
relations with Lebanon and promoting peace and stability in the region. They note that some
Lebanese consider Hezbollah a legitimate political force (it has members in the Lebanese
parliament) and that the group provides needed social services in some of Lebanon’s poorest
communities. In the past, the EU has also at times resisted U.S. calls to add suspected Hamas-
related charities to its common terrorist list; some EU members have long viewed many of these
charities as separate entities engaged in political or social work.19
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 Bush Administration essentially
determined that the political benefits of engaging the EU as an entity on police and judicial
matters outweighed the potential risks. U.S. officials suggested that the Union’s renewed
initiatives in the police and judicial field might be the first steps on a long road toward a common
EU judicial identity. Thus, they asserted it was in U.S. interests to engage with the EU, 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.
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

19 The EU has listed Hamas’ military wing on its common terrorist list since 2001, and its political wing since 2003. In
2005, the EU added two charities believed to be related to Hamas to its common terrorist list. All 27 EU member states
must agree in order for a group or individual to be added to the EU’s list.

U.S.-EU Cooperation Against Terrorism

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
EP counterparts, 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.20
