Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Summary
Pakistan’s nuclear arsenal consists of approximately 60 nuclear warheads, although it could be
larger. Islamabad is producing fissile material, adding to related production facilities, and
deploying additional delivery vehicles. These steps will enable Pakistan to undertake both
quantitative and qualitative improvements to its nuclear arsenal. Whether and to what extent
Pakistan’s current expansion of its nuclear weapons-related facilities is a response to the 2008
U.S.-India nuclear cooperation agreement is unclear. Islamabad does not have a public, detailed
nuclear doctrine, but its “minimum credible deterrent” is widely regarded as primarily a deterrent
to Indian military action.
Pakistan has in recent years taken a number of steps to increase international confidence in the
security of its nuclear arsenal. In addition to dramatically overhauling nuclear command and
control structures since September 11, 2001, Islamabad has implemented new personnel security
programs. Moreover, Pakistani and some U.S. officials argue that, since the 2004 revelations
about a procurement network run by former Pakistani nuclear official A.Q. Khan, Islamabad has
taken a number of steps to improve its nuclear security and to prevent further proliferation of
nuclear-related technologies and materials. A number of important initiatives, such as
strengthened export control laws, improved personnel security, and international nuclear security
cooperation programs have improved Pakistan’s security situation in recent years.
Instability in Pakistan has called the extent and durability of these reforms into question. Some
observers fear radical takeover of a government that possesses a nuclear bomb, or proliferation by
radical sympathizers within Pakistan’s nuclear complex in case of a breakdown of controls. While
U.S. and Pakistani officials continue to express confidence in controls over Pakistan’s nuclear
weapons, continued instability in the country could impact these safeguards. For a broader
discussion, see CRS Report RL33498, Pakistan-U.S. Relations, by K. Alan Kronstadt. This report
will be updated.

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Background
Chronic political instability in Pakistan and the current offensive against the Taliban in the
northwest of the country have called attention to the issue of the security of the country’s nuclear
weapons. Some observers fear that Pakistan’s strategic nuclear assets could be obtained by
terrorists, or used by elements in the Pakistani government. Chair of the Joint Chiefs of Staff
Admiral Michael Mullen described U.S. concern about the matter during a September 22, 2008,
speech:
To the best of my ability to understand it—and that is with some ability—the weapons there
are secure. And that even in the change of government, the controls of those weapons haven't
changed. That said, they are their weapons. They're not my weapons. And there are limits to
what I know. Certainly at a worst-case scenario with respect to Pakistan, I worry a great deal
about those weapons falling into the hands of terrorists and either being proliferated or
potentially used. And so, control of those, stability, stable control of those weapons is a key
concern. And I think certainly the Pakistani leadership that I've spoken with on both the
military and civilian side understand that.
U.S. officials continue to be concerned about the existential threat posed by nuclear weapons in a
destabilized Pakistan. General David H. Petraeus, Commander, U.S. Central Command, testified
March 31, 2009, that “Pakistani state failure would provide transnational terrorist groups and
other extremist organizations an opportunity to acquire nuclear weapons and a safe haven from
which to plan and launch attacks.”
Nevertheless, U.S. officials have generally expressed confidence in the security of Pakistan’s
nuclear weapons. President Obama addressed this issue in an April 29, 2009, press conference,
stating, “I’m confident that we can make sure that Pakistan’s nuclear arsenal is secure, primarily,
initially, because the Pakistani army, I think, recognizes the hazards of those weapons falling into
the wrong hands. We've got strong military-to-military consultation and cooperation.” He also
recognized the sensitivity of the issue for Pakistan, saying, “We want to respect their sovereignty,
but we also recognize that we have huge strategic interests, huge national security interests in
making sure that Pakistan is stable and that you don't end up having a nuclear-armed militant
state.”1 Declining to engage in “hypotheticals” when asked if the United States is ready to secure
the nuclear arsenal if the Pakistani government could not do so, President Obama said he felt
“confident that that nuclear arsenal will remain out of militant hands.”
General Petraeus reaffirmed this confidence on May 10: “With respect to the—the nuclear
weapons and—and sites that are controlled by Pakistan … we have confidence in their security
procedures and elements and believe that the security of those sites is adequate.”2 Admiral Mullen
echoed this assessment during a May 14, 2009, hearing before the Senate Armed Services
Committee, but added that “we’re limited in what we actually know” about Islamabad’s nuclear
arsenal.” Leon Panetta, Director of the Central Intelligence Agency, similarly acknowledged in a
May 18 speech that the United States does not possess the intelligence to locate all of Pakistan’s
nuclear weapons-related sites.

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Pakistani efforts to improve the security of its nuclear weapons have been on-going and include
some cooperation with the United States. Since the 1998 Pakistani and Indian nuclear tests, the
international community has increased attention to reducing the risk of nuclear war in South Asia.
The two countries most recently came to the brink of full-scale war in 1999 and 2002, and,
realizing the dangers, have developed some risk reduction measures to prevent accidental nuclear
war. Islamabad has also developed its command and control systems and improved security of
military and civilian nuclear facilities. Since the 2004 revelations of an extensive international
nuclear proliferation network run by Pakistani nuclear official Abdul Qadeer Khan, as well as
possible connections between Pakistani nuclear scientists and Al Qaeda, Islamabad has made
additional efforts to improve export controls and monitor nuclear personnel. The main security
challenges for Pakistan’s nuclear arsenal are keeping the integrity of the command structure,
ensuring physical security, and preventing illicit proliferation from insiders.
Pakistan continues to produce fissile material for weapons and appears to be augmenting its
weapons production facilities, as well as deploying additional delivery vehicles—steps that will
enable both quantitative and qualitative improvements in Islamabad’s nuclear arsenal.
Nuclear Weapons
Pakistan’s nuclear energy program dates back to the 1950s, but it was the loss of East Pakistan
(now Bangladesh) in a bloody war with India that probably triggered a political decision in
January 1972 (just one month later) to begin a secret nuclear weapons program.3 Deterring India’s
nuclear weapons and augmenting Pakistan’s inferior conventional forces are widely believed to
be the primary missions for Islamabad’s nuclear arsenal. Observers point to India’s 1974
“peaceful” nuclear explosion as the pivotal moment that gave additional urgency to the program.
Pakistan produced fissile material for its nuclear weapons using gas-centrifuge-based uranium
enrichment technology, which it mastered by the mid-1980s. Highly-enriched uranium (HEU) is
one of two types of fissile material used in nuclear weapons; the other is plutonium. The
country’s main enrichment facility is a centrifuge plant located at Kahuta; Pakistan may have
other enrichment sites.4
Islamabad gained technology from many sources. This extensive assistance is reported to have
included, among other things, uranium enrichment technology from Europe, blueprints for a
small nuclear weapon from China, and missile technology from China.
The United States had information during the 1970s and early 1980s that Pakistan was pursuing
nuclear weapons designs,5 but exactly when Pakistan produced a workable nuclear explosive
device is unclear. A 1985 National Intelligence Council report stated that Pakistan “probably has a
workable design for a nuclear explosive device” and was “probably ... a year or two away from a

capacity to produce enough” highly enriched uranium for such a device. A 1993 National Security
Council report to Congress stated that Islamabad’s nuclear weapons efforts “culminated with the
capability to rapidly assemble a nuclear device if necessary by the end of the 1980s.”6 A.Q. Khan
stated in an interview published in May 1998 that Islamabad “attained” the capability to detonate
such a device “at the end of 1984.”7 In any case, President Bush’s failure to certify in 1990 that
Pakistan did not “possess a nuclear explosive device” led to a cut-off in military and financial aid
under the Pressler Amendment.8
When India conducted nuclear weapon tests on May 12, 1998, Pakistan’s government responded
two weeks later on May 28 and May 30 with six tests in western Pakistan. Test yields were about
10 kilotons and 5 kilotons, according to seismic analysis.9 The United States imposed additional
sanctions after the tests, but these were lifted after the September 11th, 2001, terrorist attacks on
the United States. According to most public estimates, Pakistan has about 60 nuclear weapons,
though it could have more.10 However, a recent public estimate from two prominent experts on
the subject stated that the country has between 70 and 90 nuclear weapons.11 Pakistan’s nuclear
warheads use an implosion design with a solid core of approximately 15-20 kilograms of HEU.12
Islamabad reportedly continues to produce HEU for weapons at a rate of at least 100 kilograms
per year.13
Pakistan has also pursued plutonium-based warheads and continues to produce plutonium for
weapons. Islamabad has received Chinese and European assistance for at least some of its
plutonium program. The 40-50 megawatt heavy water Khushab plutonium production reactor has
been operating since 1998.14 It appears that Islamabad is constructing two additional heavy water

reactors, which will expand considerably Pakistan’s plutonium production capacity, at the same
site.15 Additionally, Pakistan has a reprocessing facility16 at the Pakistan Institute of Science and
Technology (PINSTECH) and is apparently constructing other such facilities. Nuclear Fuel
reported in 2000 that, according to “senior U.S. government officials,” Islamabad had begun
operating a “pilot-scale” reprocessing facility at the New Laboratories facility at PINSTECH.17
Pakistan also appears to be constructing a second reprocessing facility at the site 18 and may be
completing a reprocessing facility located at Chasma.19
Islamabad’s construction of additional nuclear reactors and expansion of its reprocessing
capabilities could indicate plans to increase and improve Pakistan’s nuclear weapons arsenal in
the near future. Indeed, Defense Intelligence Agency Director Michael Maples told the Senate
Armed Services Committee on March 10, 2009, that “Pakistan continues to develop its nuclear
infrastructure, expand nuclear weapon stockpiles and seek more advanced warheads and delivery
systems.”20 Similarly, Admiral Mullen confirmed during the May 14 hearing that the United
States has “evidence” that Pakistan is expanding its nuclear arsenal.
Responding to India?
Pakistani officials have indicated that they have already determined the arsenal size needed for a
minimum nuclear deterrent and that they will not engage in an arms race with India.
Nevertheless, Pakistan appears to be increasing its fissile production capability and improving its
delivery vehicles in order to hedge against possible increases in India’s nuclear arsenal. Islamabad
may also accelerate its current nuclear weapons efforts.
India has stated that it needs only a “credible minimum deterrent,” but New Delhi has never
defined what it means by such a deterrent and has refused to sign the Comprehensive Test Ban
Treaty. Furthermore, both the agreement and associated 2008 decision by the Nuclear Suppliers
Group to exempt India from some of its export guidelines will renew New Delhi’s access to the

international uranium market. This access will result in more indigenous Indian uranium available
for weapons because it will not be consumed by India’s newly safeguarded reactors.21
Pakistani officials have stated that the government may need to increase significantly its nuclear
arsenal in response to possible Indian plans to do the same. According to an April 2006 television
broadcast, Pakistani officials from the government’s National Command Authority expressed
“concern” that the 2008 U.S.-India nuclear cooperation agreement could tilt the strategic balance
between India and Pakistan in favor of the former. The officials suggested that Islamabad may
need to increase or improve its nuclear arsenal in order to “to meet all requirements of minimum
credible defence deterrence.”22 (See the “Nuclear Doctrine” section for more on Pakistan’s
deterrence concept.) Similarly, Pakistan’s Permanent Representative to the International Atomic
Energy Agency (IAEA) wrote in July 2008 that the agreement could cause a nuclear arms race
between Pakistan and India.23 Moreover, a Foreign Ministry spokesperson indicated during a May
21, 2009, press briefing that, despite the government’s continued opposition to a “nuclear or
conventional arms race in South Asia,” Pakistan may need to increase its nuclear arsenal in
response to Indian conventional and nuclear arms expansion.
Illustrating this point, a Pakistani Foreign Office spokesperson reacted to India’s July 26, 2009,
launch of its first indigenously built nuclear-powered submarine by asserting that “continued
induction of new lethal weapon systems by India is detrimental to regional peace and stability,”
adding that “[w]ithout entering into an arms race with India, Pakistan will take all appropriate
steps to safeguard its security and maintain strategic balance in South Asia.” The submarine,
which has not yet been deployed, will reportedly be capable of carrying nuclear-armed ballistic
missiles.24
However, whether and to what extent Pakistan’s current expansion of its nuclear weapons-related
facilities is a response to the U.S.-India agreement is unclear, partly because the government’s
decisions regarding those facilities are not publicly available.
In addition to making qualitative and quantitative improvements to its nuclear arsenal, Pakistan
could increase the number of circumstances under which it would be willing to use nuclear
weapons. For example, Peter Lavoy has argued that India’s efforts to improve its conventional
military capabilities could enable New Delhi to achieve “technical superiority” in Intelligence,
Surveillance, and Reconnaissance, as well as precision targeting, proving India with “the
capability to effectively locate and efficiently destroy strategically important targets in
Pakistan.”25 Islamabad could respond by lowering the threshold for using nuclear weapons,
according to Lavoy. Indeed, a Pakistan Foreign Ministry spokesperson warned in May 2009 that
Islamabad could take this step. (See the “Nuclear Doctrine” section.)

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Nevertheless, Islamabad’s nuclear weapons program apparently faces some budget constraints.
Maples testified that “the economic decline will likely slow” the government’s progress in
improving its nuclear and conventional military forces. Furthermore, Pakistan’s nuclear weapons
program is reportedly facing “severe financial cuts.”26
Delivery Vehicles
Pakistan has two types of delivery vehicles for nuclear weapons: aircraft controlled by the
Pakistan Air Force and surface-to-surface missiles controlled by the Pakistan Army. Pakistan
could deliver its nuclear weapons using F-16s purchased from the United States, provided that
modifications are made. It is widely believed that Islamabad has made modifications to the F-16s
previously sold to them.27 Although concerns have been raised about the impact of these sales on
the strategic balance in South Asia,28 the U.S. government maintains that the sale of additional F-
16s to Pakistan will not alter the regional balance of power.29 The contract for provision of an
additional 36 aircraft was signed on September 30, 2006, as was the contract for the weapons for
those aircraft and a contract to perform the mid-life upgrade on Pakistan’s F-16A/B model
aircraft. Pakistan’s F-16 fleet will therefore be expanded, but it is unclear what portion of the fleet
will be capable of a nuclear mission. Mirage III and V aircraft could also be used, although would
have limited range. A-5’s may have been modified to carry a nuclear payload.30
After India’s first test of its Prithvi ballistic missile in 1988, Pakistan jump-started its own missile
program and has three types of ballistic missiles thought to be nuclear-capable: the solid-fuel
Hatf-III (Ghaznavi), with a range of about 400 kilometers; the solid-fuel Hatf-IV (Shaheen), with
a range of over 450 kilometers31; and the liquid-fuel Hatf-V (Ghauri), with an approximate range
of almost 1,300 kilometers.32 33 The solid-fuel Hatf-VI (Shaheen-2) missile, when deployed, will
be “capable of reaching targets out to 2,000 kilometers,” Maples stated March 10,34 adding that
Islamabad has made “significant progress” on the missile. A 2009 National Air and Space
Intelligence Center report appears to support this conclusion, stating that the missile “probably

will soon be deployed.” Islamabad continues to carry out ballistic missile tests, but notifies India
in advance in accordance with an October 2005 bilateral missile pre-notification pact.35 Maples
also indicated that Pakistan is developing nuclear-capable cruise missiles; the Babur (ground-
launched) and the Ra’ad (air-launched), both of which will have estimated ranges of 320
kilometers.36
Nuclear Doctrine
Pakistan’s strategic doctrine is undeclared, and will probably remain so, but prominent officials
and analysts have offered insights concerning its basic tenets.37 Describing the guiding principle
as minimum credible nuclear deterrence, high level officials’ statements point to four policy
objectives for Islamabad’s nuclear weapons: deter all forms of external aggression; deter through
a combination of conventional and strategic forces; deter counterforce strategies by securing
strategic assets and threatening nuclear retaliation; and stabilize strategic deterrence in South
Asia.38 Pakistani officials have also indicated that this nuclear posture is designed to preserve
territorial integrity against Indian attack, prevent military escalation, and counter its main rival’s
conventional superiority.39
Pakistan has pledged no-first-use against non-nuclear-weapon states, but has not ruled out first-
use against a nuclear-armed aggressor, such as India.40 Some analysts say this ambiguity serves to
maintain deterrence against India’s conventional superiority; the Foreign Ministry spokesperson
stated May 21 that “there are acquisitions of sophisticated weaponry by our neighbour which will
disturb the conventional balance between our two countries and hence, lower the nuclear
threshold.” Other analysts argue that keeping the first-use option against New Delhi allows
Islamabad to conduct sub-conventional operations, such as support for low intensity conflict or
proxy war in Kashmir, while effectively deterring India at the strategic level.41 Pakistan has
reportedly addressed issues of survivability through pursuing a second strike capability, possibly
building hard and deeply buried storage and launch facilities, deploying road-mobile missiles,
deploying air defenses around strategic sites, and utilizing concealment measures.42

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Command and Control
Pakistan’s command and control over its nuclear weapons is compartmentalized and includes
strict operational security. The government’s command and control system is based on “C4I2SR”
(command, control, communication, computers, intelligence, information, surveillance and
reconnaissance). Islamabad’s Strategic Command Organization has a three-tiered structure,
consisting of the National Command Authority (NCA), the Strategic Plans Division (SPD), and
the Strategic Forces Commands.
The NCA supervises the functions and administration of all of Pakistan’s organizations involved
in nuclear weapons research, development, and employment, as well as the military services that
operate the strategic forces.43 The President is Chairperson of the NCA; the Prime Minister is the
Vice-Chairperson. The NCA also includes the chair of the joint chiefs of staff, the Ministers of
Defense, Interior, and Finance, the Director- General of the SPD, and the Commanders of the
Army, Air Force, and Navy. The final authority to launch a nuclear strike requires consensus
within the NCA; the Chairperson must cast the final vote. The NCA is comprised of two
committees, the Employment Control Committee (ECC) and the Development Control
Committee (DCC), each of which includes a mix of civilian and military officials. The ECC’s
functions include establishing a command and control system over the use of nuclear weapons.
The DCC “exercises technical, financial and administrative control over all strategic
organisations, including national laboratories and research and development organisations
associated with the development and modernisation of nuclear weapons.”44
The SPD is headed by a Director General from the Army and acts as the secretariat for the NCA.
The SPD’s functions include formulating Islamabad’s nuclear policy, strategy, and doctrine;
developing the nuclear chain of command; and formulating operational plans at the service level
for the movement, deployment, and use of nuclear weapons. The Army, Air Force, and Navy each
have their own strategic force command, but operational planning and control remains with the
NCA. The SPD coordinates operational plans with the strategic forces commands. According to
current and former Pakistani officials, Islamabad employs a system which requires that at least
two, and perhaps three, people authenticate launch codes for nuclear weapons. 45
On December 13, 2007, President Musharraf formalized these authorities and structure in the
“National Command Authority Ordinance, 2007.”46 The NCA was established by administrative
order, but now has a legal basis. Analysts point out that the timing of this ordinance was meant to
help the command and control system weather political transitions and potentially preserve the
military’s strong control over the system. The ordinance also addresses the problems of the

proliferation of nuclear expertise and personnel reliability. It outlines punishable offenses related
to breach of confidentiality or leakage of “secured information,” gives the SPD authority to
investigate suspicious conduct, states that punishment for these offenses can be up to 25 years
imprisonment, and applies to both serving and retired personnel, including military personnel,
notwithstanding any other laws. As a result, Pakistani authorities say that the ordinance should
strengthen their control over strategic organizations and their personnel.
Security Concerns
According to a 2001 Department of Defense report, Islamabad’s nuclear weapons “are probably
stored in component form,”47 which suggests that the nuclear warheads are stored separately from
delivery vehicles. According to some reports, the fissile cores of the weapons are separated from
the non-nuclear explosives.48 But whether this is actually the case is unclear; one report states that
the warheads and delivery vehicles are probably stored separately in facilities close to one
another, but says nothing about the fissile cores.49 And, according to an account of a 2008 experts’
group visit to Pakistan, Lt. Gen. Khalid Kidwai, the head of the SPD, suggested that the nuclear
warheads (containing the fissile cores) may be mated with their delivery vehicles.50 According to
Kidwai, the report says, the SPD’s official position is that the weapons “will be ready when
required, at the shortest notice; [but] the Pakistani doctrine is not endorsing a US-USSR model
with weapons on hair trigger alert.” The 2001 Defense Department report says that Pakistan can
probably assemble its weapons fairly quickly.51
Although separate storage may provide a layer of protection against accidental launch or prevent
theft of an assembled weapon, it may be easier for unauthorized people to remove a weapon’s
fissile material core if it is not assembled. Dispersal of the assets may also create more potential
access points for acquisition and may increase the risk of diversion.52
As the United States prepared to launch an attack on the Afghan Taliban after September 11,
2001, President Musharraf reportedly ordered that Pakistan’s nuclear arsenal be redeployed to “at
least six secret new locations.”53 This action came at a time of uncertainly about the future of the
region, including the direction of U.S.-Pakistan relations. Islamabad’s leadership was uncertain
whether the United States would decide to conduct military strikes against Pakistan’s nuclear
assets if the government did not assist the United States against the Taliban. Indeed, President

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Musharraf cited protection of Pakistan’s nuclear and missile assets as one of the reasons for
Islamabad’s dramatic policy shift.54
These events, in combination with the 1999 Kargil crisis, the 2002 conflict with India at the Line
of Control, and revelations about the A.Q. Khan proliferation network, inspired a variety of
reforms to secure the nuclear complex. Risk of nuclear war in South Asia ran high in the 1999
Kargil crisis, when the Pakistani military is believed to have begun preparing nuclear-tipped
missiles.55 It should be noted that, even at the high alert levels of 2001 and 2002, there were no
reports of Pakistan mating the warheads with delivery systems.56
In the fall of 2007 and early 2008, some observers expressed concern about the security of the
country’s arsenal if political instability were to persist.57 Former Prime Minister Benazir Bhutto
said in an interview on November 5, 2007, that while President Musharraf says he is firm control
of the nuclear arsenal, she is afraid this control could weaken due to instability in the country.58
Similarly, Michael Krepon of the Henry L. Stimson Center has argued that “a prolonged period of
turbulence and infighting among the country’s President, Prime Minister, and Army Chief” could
jeopardize the army’s unity of command, which “is essential for nuclear security.”59 During that
time, U.S. military officials also expressed concern about the security of Pakistan’s nuclear
weapons.60 Director General of the International Atomic Energy Agency (IAEA), Mohamed
ElBaradei, also has expressed fears that a radical regime could take power in Pakistan, and
thereby acquire nuclear weapons.61 Experts also worry that while nuclear weapons are currently
under firm control, with warheads disassembled, technology could be sold off by insiders during
a worsened crisis.62
However, U.S. intelligence officials have expressed greater confidence regarding the security of
Islamabad’s nuclear weapons. Deputy Secretary of State John D. Negroponte in testimony to
Congress on November 7, 2007 said he believed that there is “plenty of succession planning that’s
going on in the Pakistani military” and that Pakistan’s nuclear weapons are under “effective
technical control.”63 Similarly, Donald Kerr, Principal Deputy Director of National Intelligence,
told a Washington audience May 29, 2008, that the Pakistani military’s control of the country’s

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

nuclear weapons is “a good thing because that’s an institution in Pakistan that has, in fact,
withstood many of the political changes over the years.” A Department of Defense spokesperson
told reporters December 9, 2008, that Washington has “no reason at this point to have any
concern with regards to the security” of Islamabad’s nuclear arsenal. More recently, Maples stated
March 10 that Islamabad “has taken important steps to safeguard its nuclear weapons,” but also
pointed out that “vulnerabilities exist.”
Other governments have also voiced opinions regarding the security of Pakistan’s nuclear arsenal.
For example, Indian National Security Adviser M. K. Narayanan said that the arsenal is safe and
has adequate checks and balances.64 Similarly, Secretary of State for Foreign and Commonwealth
Affairs David Miliband told the Charlie Rose Show December 15, 2008, that Islamabad’s nuclear
weapons “are under pretty close lock and key.” Russian Deputy Prime Minister Sergei Ivanov,
however, sounded somewhat less optimistic in a March 24, 2009, television interview, stating that
Moscow is “very much concerned” about the security of Pakistan’s arsenal.65
Pakistani officials have consistently expressed confidence in the security of the country’s nuclear
arsenal. Then-President Musharraf stated in November 2007 that Pakistan’s nuclear weapons are
under “total custodial controls.”66 More recently, President Asif Ali Zardari told CNN December
2, 2008, that the country’s nuclear command and control system “is working well.” Additionally,
a Pakistani Foreign Ministry spokesperson stated May 21, 2009, that “there is simply no question
of our strategic assets falling into the wrong hands. We have full confidence in our procedures,
mechanisms and command and control systems.”
In addition to the above scenarios, the security of Pakistan’s nuclear weapons could also be
jeopardized by another conflict between India and Pakistan, Michael Krepon argued, explaining
that an “escalating war with nuclear forces in the field would increase the probability of
accidents, miscalculations, and the use of nuclear weapons.” This is because
[w]hen tensions rise precipitously with India, the readiness level of Pakistan’s nuclear
deterrent also rises. Because the geographical coordinates of Pakistan’s main nuclear weapon
storage sites, missile, and air bases can be readily identified from satellites—and therefore
targeted by opposing forces—the dictates of deterrence mandate some movement of
launchers and weapons from fixed locations during crises. Nuclear weapons on the move are
inherently less secure than nuclear weapons at heavily-guarded storage sites. Weapons and
launchers in motion are also more susceptible to “insider” threats and accidents.67
Such a war, Krepon added, would also place stress on the army’s unity of command. Krepon has
also pointed out that Islamabad faces a dilemma, because less-dispersed nuclear weapons may be
more vulnerable to a disarming military strike from India.68
U.S. plans to secure Pakistani nuclear weapons in case of a loss of control by the Pakistani
government were famously addressed during Secretary of State Condoleezza Rice’s confirmation
hearing in January 2005. In response to a question from Senator John Kerry asking what would

happen to Pakistan’s nuclear weapons in the event of a radical Islamic coup in Islamabad,
Secretary Rice answered, “We have noted this problem, and we are prepared to try to deal with
it.”69 On November 12, 2007, responding to press reports about this contingency, a Pakistan
Foreign Office spokesperson said, “Pakistan possesses adequate retaliatory capacity to defend its
strategic assets and sovereignty,” emphasizing that Islamabad’s nuclear weapons have been under
“strong multi-layered, institutionalized decision-making, organizational, administrative and
command and control structures since 1998.” 70 The issue of U.S. contingency plans to take over
Pakistani strategic assets was raised again in the press following Benazir Bhutto’s assassination,
and was met with similar assurances by Pakistan’s government.71
The United States reportedly offered Pakistan nuclear security assistance soon after September
11th, 2001.72 U.S. assistance to Islamabad, which must comply with nonproliferation guidelines,
has reportedly included the sharing of best practices and technical measures to prevent
unauthorized or accidental use of nuclear weapons, as well as contribute to physical security of
storage facilities and personnel reliability.73 Some press reports say that the United States
provided Pakistan with Permissive Action Links (PALs) in 2003, although former Pakistani
military officials have said Pakistan has developed PALs for its warheads without assistance.74
PALs require a code to be entered before a weapon can be detonated. As noted above, Islamabad
employs a system requiring that at least two, and perhaps three, people authenticate launch codes
for nuclear weapons.75 Security at nuclear sites in Islamabad is the responsibility of a 10,000-
member security force, commanded by a two-star general.
Former Deputy Secretary of State Richard Armitage confirmed in a November 2007 interview
that there has been U.S. assistance in this area, explaining that the United States was unlikely to
intervene militarily in a crisis in Pakistan because “we have spent considerable time with the
Pakistani military, talking with them and working with them on the security of their nuclear
weapons. I think most observers would say that they are fairly secure. They have pretty
sophisticated mechanisms to guard the security of those.”76 Rolf Mowatt-Larssen, former Director
of the Office of Intelligence and Counterintelligence at the U.S. Department of Energy, pointed

out in May 2009 that “there’s not a lot of transparency into” how Islamabad spends the U.S.
funds, but he nevertheless characterized them as “money well spent.”77
The U.S. government has also reportedly offered assistance to secure or destroy radioactive
materials that could be used to make a radioactive dispersal device, and to ship highly enriched
uranium used in the Pakistani civilian nuclear sector out of the country.78 It is not clear what
Pakistan’s response has been to these proposals.
It is worth noting that, according to some observers, spent fuel from Pakistan’s Karachi and
Chasma nuclear power plants could be vulnerable to theft or attack.79 Pakistani officials have
expressed confidence in the security of its facilities, however.80
Proliferation Threat
Many observers are concerned that other states or terrorist organizations could obtain material or
expertise related to nuclear weapons from Pakistan.81 Beginning in the 1970s, Pakistan used
clandestine procurement networks to develop its nuclear weapons program. Former Pakistani
nuclear official A.Q. Khan subsequently used a similar network to supply Libya, North Korea,
and Iran with materials related to uranium enrichment.82
Al-Qaeda has also sought assistance from the Khan network. According to former Director of
Central Intelligence George Tenet, the United States “received fragmentary information from an
intelligence service” that in 1998 Osama bin Laden had “sent emissaries to establish contact”
with the network.83 Other Pakistani sources could also provide nuclear material to terrorist
organizations. According to a 2005 report by the Commission on the Intelligence Capabilities of
the United States Regarding Weapons of Mass Destruction, al-Qaeda “had established contact
with Pakistani scientists who discussed development of nuclear devices that would require hard-
to-obtain materials like uranium to create a nuclear explosion.”84 Tenet explains that these
scientists were affiliated with a different organization than the Khan network.
The current status of Pakistan’s nuclear export network is unclear, although most official U.S.
reports indicate that, at the least, it has been damaged considerably. Director of National
Intelligence John D. Negroponte implied that the network had been dismantled when he asserted

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

in a January 11, 2007, statement to the Senate Select Committee on Intelligence that “Pakistan
had been a major source of nuclear proliferation until the disruption of the A.Q. Khan network.”85
More recently, a January 12, 2009, State Department press release said that the network “is no
longer operating.” For its part, Pakistan’s Foreign Office stated February 7, 2009, that Pakistan
“has dismantled the nuclear black market network.” Asked during a July 20, 2009, interview
whether North Korea was transferring “nuclear weapons” or related advice to North Korea,
Secretary of State Hillary Clinton replied that there is “no evidence” that Pakistan is doing so.
However, when asked about the network’s current status during a July 25, 2007, Senate Foreign
Relations Committee hearing, Undersecretary for Political Affairs Nicholas Burns replied that:
I cannot assert that no part of that network exists, but it’s my understanding based on our
conversations with the Pakistanis that the network has been fundamentally dismantled. But
to say that there are no elements in Pakistan, I’m not sure I could say that.
Similarly, the London-based International Institute for Strategic Studies found in a May 2007
report that “at least some of Khan’s associates appear to have escaped law enforcement attention
and could ... resume their black-market business.”86
Asked about Pakistan’s cooperation in investigating the network, Burns acknowledged that the
United States has not had “personal, consistent access” to Khan, but added that he did not “have
all the details of everything we’ve done.” Similarly, the IAEA has not yet been able to interview
Khan directly, according to an agency official. However, Islamabad has responded to written
questions from the IAEA and has been cooperative with the agency’s investigation of Iran’s
nuclear program.87 Khan himself told Dawn News TV May 29, 2008, that he would not cooperate
with U.S. or IAEA investigators. A Pakistani Foreign Office spokesperson told reporters in May
2006 that the government considered the Khan investigation “closed”—a position an Office
spokesperson reiterated February 6, 2009.
The State Department announced January 12, 2009, that it was imposing sanctions on 13
individuals and three companies for their involvement in the Khan network. The sanctions were
imposed under the Export-Import Bank Act, the Nuclear Proliferation Prevention Act, and
Executive Orders 12938 and 13382.
Pakistan’s Response to the Proliferation Threat
Undersecretary Burns testified in July 2007 that the Bush administration has “told the Pakistani
government that it is its responsibility ... to make sure” that neither the Khan network nor a
“similar organization” resurfaces in the country. Since the revelations about the Khan network,
Pakistan appears to have increased its efforts to prevent nuclear proliferation. But whether and to
what extent these efforts have been successful is not yet clear. It is worth noting that, because
Khan conducted his proliferation activities as a government official, they do not necessarily
indicate a failure of Islamabad’s export controls.

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

Pakistani officials argue that Islamabad has taken a number of steps to prevent further
proliferation of nuclear-related technologies and materials.88 For example, Islamabad adopted in
September 2004 new national export controls legislation which includes a requirement that the
government issue control lists for “goods, technologies, material, and equipment which may
contribute to designing, development, stockpiling, [and] use” of nuclear weapons and related
delivery systems. According to a February 2008 presentation by Zafar Ali, Director of Pakistan’s
Strategic Export Controls Division (SECDIV),89 the lists, which were issued in October 2005 and
are to be periodically updated, include items controlled by multilateral export control regimes,
such as the Nuclear Suppliers Group, the Australia Group, and the Missile Technology Control
Regime.90 The export controls legislation also includes a catch-all clause, which requires
exporters to notify the government if they are aware or suspect that goods or technology are
intended by the end-user for use in nuclear or biological weapons, or missiles capable of
delivering such weapons.91
The legislation includes several other important elements, such as end-use and end-user
certification requirements and new penalties for violators. Since its adoption, Pakistan has
established the SECDIV and an associated Oversight Board. The SECDIV is responsible for
formulating rules and regulations for implementing the legislation. The board is comprised of
officials from multiple agencies and is headed by Pakistan’s Foreign Secretary.
Islamabad says that it has also taken several other steps to improve its nuclear security. For
example, the government announced in June 2007 that it is “implementing a National Security
Action Plan with the [IAEA’s] assistance.” That same month, Pakistan also joined the U.S.- and
Russian-led Global Initiative to Combat Nuclear Terrorism. As noted above, the December 2007
National Command Authority Ordinance also includes measures to prevent the spread of nuclear-
related materials and expertise.
Pakistani officials participating in an April 2007 Partnership for Global Security workshop argued
that Islamabad has improved the reliability of its nuclear personnel by, for example, making
security clearance procedures more stringent. However, the officials also acknowledged that
Islamabad still needs to do more to control its nuclear expertise.92 Similarly, Admiral Mullen
stated May 14, 2009, that the country’s personnel reliability system must “continue to improve.”

88 Details of Pakistan’s nuclear-related legislation can be found in the country’s reports to the UN 1540 Committee.

Pakistan,” February 21-22, 2008. http://www.partnershipforglobalsecurity.org/documents/zafar_export.pdf.
90 The Nuclear Suppliers Group is a multilateral, voluntary group of nuclear supplier states which have agreed to
coordinate their exports of civilian nuclear technology and materials in order to prevent importers from using them to
produce nuclear weapons. The Australia Group is a voluntary, informal, export-control arrangement through which
participating countries coordinate their national export controls to limit the supply of chemicals and biological agents,
as well as related equipment, technologies, and knowledge, to countries and nonstate entities suspected of pursuing
chemical or biological weapons capabilities. The Missile Technology Control Regime is an informal, voluntary
arrangement in which participants agree to adhere to common export policy guidelines applied to an “annex” that lists
items related to the proliferation of ballistic and cruise missiles, rockets, and unmanned air vehicles capable of
delivering weapons of mass destruction.

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

The United States has also provided export control assistance to Pakistan. Burns described several
such efforts in his July 2007 testimony.93 And according to an October 2007 U.S. Government
Accountability Office report, Islamabad was during FY2003-FY2006 the second-largest recipient
of bilateral U.S. assistance designed to improve target countries’ export controls. Pakistan
received such assistance from the Departments of State, Energy, and Homeland Security.94
Under Secretary of State for Arms Control and International Security-Designate Ellen Tauscher
told the Senate Foreign Relations Committee that the Obama administration does not support
conditioning aid to Pakistan on permitting direct U.S. access to Khan, arguing, in part, that the
United States has “obtained a great deal of information about the Khan network without having
direct access to A.Q. Khan.”95
Issues for Congress
Members of Congress have also expressed concerns regarding the security of Pakistan’s nuclear
weapons and related material. Senator Richard Lugar has spoken out in favor of using the
cooperative threat reduction tools in Pakistan to help with the security of nuclear, biological, and
chemical materials and weapons in the country.96
Additionally, a number of pieces of legislation appear designed to influence Islamabad’s policies
regarding the Khan network. Section 2 of H.R. 1463, which was introduced March 12, 2009, and
referred to the House Foreign Affairs Committee the same day, states that U.S. military assistance
may be provided to Pakistan only if the President certifies that Islamabad is both making A.Q.
Khan available to the United States for questioning and “providing adequate assurances to the
United States Government that it will monitor Khan’s movements and activities in such a manner
as to prevent his participation in any efforts to disseminate nuclear technology or know-how.”
This section allows the President to waive restrictions on U.S. assistance imposed pursuant to the
proposed legislation if the President “certifies to Congress that it is in the national interests of the
United States to do so.”
H.R. 2481, the United States-Pakistan Security and Stability Act, which was introduced May 19,
2009, and referred the same day to the House Foreign Affairs Committee, the House Armed
Services Committee, and the House Intelligence Committee, would require the President to
“develop and transmit to the appropriate congressional committees a comprehensive interagency
strategy and implementation plan for long-term security and stability in Pakistan.” The strategy is
to include a “description of how United States assistance” authorized by the bill “will be used to

these programs, “the United States and Pakistan worked together to install screening and radiation detection equipment
to scan U.S.-bound cargo.” He also stated that the Department of Energy “is working with Pakistan on radiation source
security and is in the process of finalizing an agreement to install radiation detection equipment at Pakistani ports and
border crossings.”

Pakistan’s Nuclear Weapons: Proliferation and Security Issues

achieve the objectives of United States policy toward Pakistan,” one of which is “to empower and
enable” Islamabad to “maintain robust command and control over its nuclear weapons
technology.” The bill would authorize foreign assistance for Pakistan, including funds for
improving the government’s counter-insurgency capability.
H.R. 1886, the Pakistan Enduring Assistance and Cooperation Enhancement Act of 2009, would
authorize U.S. assistance to Pakistan for a variety of purposes. These include strengthening
democratic institutions and law enforcement, as well as supporting economic development,
education, human rights, and heath care. The bill would also authorize additional U.S. security
assistance for Islamabad. However, Section 206 of the bill places conditions on some of this
assistance; it states that no U.S. military assistance shall be provided to Pakistan if the President
has not made a series of determinations, one of which is that the government “is continuing to
cooperate with the United States in efforts to dismantle supplier networks relating to the
acquisition of nuclear weapons related materials, including, as necessary, providing access to
Pakistani nationals associated with such networks.” The section includes a national security
waiver. The bill also requires a report to Congress that includes a “description of Pakistan’s
efforts to prevent proliferation of nuclear-related material and expertise” and an “assessment of
whether assistance provided to Pakistan pursuant to this Act has directly or indirectly aided the
expansion of Pakistan’s nuclear weapons program.” The committee report underlines continuing
concerns about getting full information about the activities of the Khan network and development
of Pakistan’s own nuclear arsenal:
Pakistan’s history of nuclear development and Dr. Abdul Qadeer Khan’s establishment of a
nuclear proliferation network remain a source for concern to many in the United States,
particularly since the Committee understands that representatives of the United States have
not interviewed certain individuals involved in the network. The Committee believes the
United States should continue to engage the Government of Pakistan on the network, and
should, as necessary, obtain direct access to the individuals covered by this subsection,
including Dr. Khan. The Committee also maintains strong concerns regarding recent reports
of Pakistan expansion of its nuclear arsenal. Given the expanding threat of Pakistan’s
domestic insurgency, the Government of Pakistan’s further development of nuclear materials
appears inconsistent with its immediate security threats and is unhelpful in the context of
efforts to strengthen U.S.-Pakistani relations.
H.R. 1886 was introduced April 2, 2009, and referred the same day to both the House Foreign
Affairs Committee and Rules Committee. The Foreign Affairs Committee reported the bill May
22, and the Rules Committee discharged it the same day. The bill was referred to the House
Armed Services Committee May 22 and discharged June 2. On June 11, the House passed H.R.
1886, which was appended to H.R. 2410, the Foreign Relations Authorization Act, Fiscal Years
2010 and 2011. H.R. 2410 has been received by the Senate and referred to the Senate Foreign
Relations Committee.
The Senate passed the Enhanced Partnership with Pakistan Act of 2009 (S. 962) unanimously on
June 24, 2009. This bill would provide aid to Pakistan but does not include conditions regarding
the nuclear nonproliferation or nuclear weapons activities. The Senate report (111-033) says that
“Any use of funds contained in this legislation for the purpose of augmenting Pakistan’s nuclear
weapons program would be directly contrary to Congressional intent.”
S. 1707, the Enhanced Partnership with Pakistan Act of 2009 represents a compromise between
H.R. 1886 and S. 962. It passed the Senate by unanimous consent on September 24, 2009. The
House will consider the bill on September 30. Section 203 (c) of S. 1707 requires that the

President certifies that Pakistan is “continuing to cooperate with the United States in efforts to
dismantle supplier networks relating to the acquisition of nuclear weapons-related materials, such
as providing relevant information from or direct access to Pakistani nationals associated with
such networks.” It also requires a Semi-Annual Monitoring Report that would include a detailed
description of Pakistan’s nuclear non-proliferation efforts and an assessment of whether
assistance has “directly or indirectly aided the expansion of Pakistan’s nuclear weapons program,
whether by the diversion of United States assistance or the reallocation of Pakistan’s financial
resources that would otherwise be spent for programs and activities unrelated to its nuclear
weapons program.”
