Nuclear weapons and Pakistan

Nuclear weapons and Pakistan. Pakistan is a declared nuclear weapons state, having conducted its first public tests in May 1998 in direct response to tests by its regional rival, India. The program's development, led by scientists like Abdul Qadeer Khan, has been a central element of national security policy, fundamentally shaping its strategic posture and international relations. Pakistan maintains a policy of credible minimum deterrence, primarily focused on countering conventional and nuclear threats from India, and possesses a growing arsenal of warheads and diverse delivery systems.

History of Pakistan's nuclear program

The genesis of Pakistan's nuclear program can be traced to its defeat in the Indo-Pakistani War of 1971 and India's "Smiling Buddha" nuclear test in 1974. Under the leadership of Prime Minister Zulfikar Ali Bhutto, who famously stated Pakistan would develop nuclear capability even if it meant eating grass, the program accelerated significantly. Scientist Abdul Qadeer Khan, who brought centrifuge designs from URENCO in the Netherlands, became pivotal in establishing the uranium enrichment route at the Kahuta Research Laboratories. Parallel efforts in plutonium production were pursued at the Pakistan Atomic Energy Commission (PAEC) under Munir Ahmad Khan. The program saw critical external assistance from China, particularly in warhead design, and covert procurement networks operated during the Soviet–Afghan War with tacit support from the United States. The program culminated in a series of tests in May 1998, codenamed Chagai-I and Chagai-II, conducted in the Ras Koh Hills in Balochistan in response to India's Pokhran-II tests.

Nuclear doctrine and policy

Pakistan's official nuclear doctrine is anchored in the concept of credible minimum deterrence, with a primary focus on deterring aggression from India. This posture includes a declared policy of first use, explicitly reserved for responding to a large-scale conventional attack that threatens Pakistan's territorial integrity. The doctrine is dynamic and has evolved to include the development of tactical nuclear weapons, such as the Nasr short-range ballistic missile, as part of a Full Spectrum Deterrence posture aimed at countering India's Cold Start Doctrine. Strategic planning is deeply influenced by the enduring conflict over Kashmir and the perceived conventional military asymmetry with India. Statements from the National Command Authority (NCA) and the Strategic Plans Division (SPD) consistently emphasize restraint and responsibility while maintaining the credibility of the deterrent.

Capabilities and arsenal

Pakistan is estimated to possess approximately 170 nuclear warheads, with a stockpile that is growing faster than any other country's. The arsenal relies on two fissile material cores: highly enriched uranium and weapons-grade plutonium, produced at facilities like the Khushab Nuclear Complex. Delivery systems are diverse and increasingly sophisticated. Land-based missiles include the short-range Abdali and Ghaznavi, the medium-range Shaheen-I, Shaheen-II, and Ghauri missiles, and the longer-range Shaheen-III capable of reaching all of India. The air leg is served by aircraft like the F-16 Fighting Falcon and Mirage 5/III, while a sea-based deterrent is under development with the Babur cruise missile and plans for a submarine-launched variant. Warheads are believed to be stored in a de-mated form, separate from their delivery vehicles.

Command and control

Authority over nuclear weapons rests with the National Command Authority (NCA), chaired by the Prime Minister and including key military and civilian leaders. The operational arm is the Strategic Plans Division (SPD), a secretive military agency responsible for security, strategic communications, and the physical custody of warheads. The SPD oversees a dedicated security force and employs a rigorous personnel reliability program. The system is designed to ensure centralized political control while enabling a swift military response if authorized. Procedures involve multiple layers of authentication and are structured to prevent unauthorized use, with launch codes believed to be held by the senior military leadership, including the Chief of Army Staff.

International relations and non-proliferation

Pakistan's nuclear status has profoundly shaped its foreign policy, particularly with the United States and China. It remains outside the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), arguing the treaty is discriminatory, and is not a signatory to the Comprehensive Nuclear-Test-Ban Treaty. Relations with the U.S. have oscillated between strategic partnership, especially during the War in Afghanistan (2001–2021), and severe strain due to non-proliferation concerns, leading to sanctions under laws like the Pressler Amendment. The exposure of the Abdul Qadeer Khan network's proliferation activities to states like North Korea, Iran, and Libya caused a major international crisis. Pakistan engages with initiatives like the Nuclear Security Summit and maintains a strategic partnership with China, which includes cooperation on civilian nuclear technology under International Atomic Energy Agency safeguards.

Controversies and security concerns

The program has been mired in significant controversies, most notably the proliferation activities of the Abdul Qadeer Khan network, which sold centrifuge technology and designs to several countries. Persistent concerns from the international community focus on the security of the arsenal, especially given internal instability, the threat of terrorism from groups like the Tehrik-i-Taliban Pakistan, and potential insider threats. The strategic arms race with India, characterized by developments in missile defense and multiple independently targetable reentry vehicle (MIRV) technology, raises risks of escalation and a crisis instability in South Asia. Furthermore, the deployment of tactical nuclear weapons is viewed by many analysts as lowering the threshold for nuclear use during a conventional conflict.
