This past Thursday and Friday marked the 6^th bi-annual Article XIV Conference, the Conference on Facilitating the Entry Into Force of the Comprehensive Nuclear Test Ban Treaty (CTBT).  This year’s conference was held at the United Nations in New York and was met with a measure of cautious optimism – most states voiced their appreciation of President Obama’s pledge to work toward US ratification of the CTBT, while many states recognized the challenges of obtaining all the necessary ratifications for entry into force of the Treaty and mentioned the challenges to the nonproliferation regime stemming from the lack of the Treaty’s entry into force (despite former commitments to do so) and from the DPRK’s 2006 and 2009 nuclear tests.

Entry into force of the CTBT has been on the international agenda for thirteen years. Because the US, China, UK, France, and Russian Federation have all imposed a voluntary moratorium on national nuclear testing, many question the need for entry into force of the CTBT.  Although the Treaty would bring few new tangible benefits, the political impact of entry into force would be tremendous.  As explained below, the vast majority of sates see entry into force of the CTBT as somewhat of a litmus test for the future viability of the nonproliferation regime.

On Friday, President Obama announced that the United States knows of a new, undeclared, and hidden underground gas-centrifuge uranium enrichment facility in Iran, near the city of Qom.  Some news reports suggest that 3000 centrifuges will be housed there.  How significant is this discovery?  Well, just in time, our crack FAS researcher, Ivanka Barzashka, has posted on the FAS website a calculator to help you answer questions just like that.

President Obama has once again pushed nuclear weapons, and his vision for a world free of nuclear weapons, to the center of the world’s stage with his speech yesterday before the United Nations’ General Assembly and his chairing of the United Nations’ Security Council meeting this morning. He reiterated his goal of ratifying the Comprehensive Test Ban Treaty (CTBT), of negotiating a Fissile Material Cutoff Treaty (FMCT) that would end production of bomb-grade nuclear material (something the Bush administration supported in theory but without any verification procedures), of negotiating a treaty with Russia that will “substantially reduce” strategic nuclear warheads, and of strengthening the Non-Proliferation Treaty (NPT). The President also said “We will complete a Nuclear Posture Review that opens the door to deeper cuts, and reduces the role of nuclear weapons.” This morning, as chair of the UN Security Council, the President got unanimous consent to Council resolution that endorsed all the points made before the General Assembly.

The President’s remarks are powerful and plain and were overwhelming well received by all of us who have long hoped that the world might someday be free of nuclear weapons. Still, I am worried that the message has been clearer at the UN, and in Prague, than it is here in Washington. If we look at the direction the bureaucracy and politics are taking here, there is reason to worry that the President’s vision will be dangerously diluted. Continue reading »

Pakistan’s nuclear weapons stockpile now includes an estimated 70-90 nuclear warheads, according to the latest Nuclear Notebook published in the Bulletin of the Atomic Scientists. The estimate is an increase compared with the previous estimate of approximately 60 warheads due to Pakistan’s pending introduction of a new ballistic missile and cruise missiles.

The increase in the warhead estimate does not mean Pakistan is thought to be sprinting ahead of India, which is also increasing its stockpile. Continue reading »

The French nuclear-powered aircraft carrier Charles de Gaulle with air wing on deck.

By Hans M. Kristensen

France no longer deploys nuclear weapons on its aircraft carrier Charles de Gaulle under normal circumstances but stores the weapons on land, according to French officials.

President Nicolas Sarkozy declared in March 2008 that France “could and should be more transparent with respect to its nuclear arsenal than anyone ever has been.” But while the other nuclear powers declared long ago that their naval weapons were offloaded or scrapped after the Cold War ended, a similar announcement has – to my knowledge – been lacking from France.

The French acknowledgment marks the end of peacetime deployment of short-range nuclear weapons at sea.

It is not clear when the French offload occurred; it may have been instigated years ago. But it completes a worldwide withdrawal of short-range nuclear weapons from the world’s oceans that 20 years ago included more than 6,500 British, French, Russian, and U.S. cruise missiles, anti-submarine rockets, anti-aircraft missiles, depth bombs, torpedoes and bombs.

Retirement of the W62 warhead will be completed in 2009.

By Hans M. Kristensen

The U.S. State Department has confirmed the estimate made by FAS on this blog in February that the United States had already reached the limit of 2,200 operationally deployed strategic nuclear warheads set by the 2002 Moscow Treaty. The confirmation occurred earlier today in a fact sheet published on the State Department’s web site: “As of May 2009, the United States had cut its number of operationally deployed strategic nuclear warheads to 2,126.”

This is a reduction of 77 warheads from the 2,203 operationally deployed strategic nuclear warheads deployed on February 5, 2009, and probably reflects the ongoing retirement of the W62 warhead from the Minuteman III ICBM force, scheduled for completion later this year.

The total U.S. nuclear weapons stockpile includes approximately 5,200 warheads.

There is cause for cautious optimism after Presidents Obama and Medvedev signed their START follow-on Joint Understanding in Moscow last Monday – the goal of completing a legally binding bilateral nuclear disarmament agreement with verification measures is preferable to letting START expire without an agreement or without one that keeps some sort of verification protocol.  The Joint Understanding leaves some familiar questions open, such as the lack of definition of a “strategic offensive weapon” and what to do about the thousands of nuclear warheads in reserve or awaiting dismantlement.  But so far few analysts on either side of the nuclear debate have been talking about the big picture, what for the vast majority of the world (and therefore our own national security) is really at stake here – the viability of the nonproliferation regime itself.

A recently released report, U.S. Nuclear Deterrence in the 21^st Century:  Getting It Right, by the ad hoc New Deterrent Working Group with a forward by James Woolsey, is an interesting document.  I believe this report is significant because it might typify the arguments that will be used against arms control treaties in the upcoming Senate debates.

Presidents Obama and Medvedev sign a joint understanding on a START follow-on treaty.

By Hans M. Kristensen

The Joint Understanding for the START Follow-on Treaty signed by President Obama and Medvedev on July 6, 2009, commits the United States and Russia to “reduce their strategic warheads to a range of 1500-1675, and their strategic delivery vehicles to a range of 500-1100.”

Negotiators will still have to hammer out the details and draft a new treaty that the presidents can sign, hopefully by the end of the year, to be implemented in seven years.

The Summit was a good effort to revive U.S.-Russian relations, but seven years is a very long timeline for a START follow-on that doesn’t force either side to change very much. Does it rule out deeper cuts for the rest of the Obama administration? Continue reading »
