Hans M. Kristensen and Robert S. Norris of FAS Strategic Security Blog report (17 July 2011) that Pakistan’s nuclear arsenal has doubled since 2004 and could double again in the next 10 years if the current trend continues. Kristensen and Norris continue:
“The latest Nuclear Notebook on Pakistan’s nuclear forces is available on the Bulletin of the Atomic Scientists web site. Since our previous Notebook on Pakistan in 2009 there have been several important developments.
Based on our own estimates, official statements, and fissile material production estimates produced by the International Panel of Fissile Materials, we conclude that Pakistan’s current nuclear weapons stockpile of 90-110 warheads might increase to 150-200 within the next decade. This would bring the Pakistani stockpile within range of the British stockpile, the smallest of the original five nuclear weapon states, but still far from that of France (despite some recent news reports to the contrary).
This development is precipitated by the anticipated introduction of several new nuclear delivery systems over the next years, including cruise missiles and short-range ballistic missiles. The capabilities of these new systems will significantly change the composition and nature of Pakistan’s nuclear posture.
India is following this development closely and is also modernizing its nuclear arsenal and fissile material production capability. The growing size, diversity, and capabilities of the Pakistani and Indian nuclear postures challenge their pledge to only acquire a minimum deterrent. Bilateral arms control talks and international pressure are urgently needed to halt what is already the world’s fastest growing nuclear arms race."
