Tactical Nukes and the NPR

The confluence of the Nuclear Posture Review (NPR) and Strategic Arms Reduction Treaty (START) negotiations has brought U.S. tactical nuclear weapons to the fore again. Two recent stories drew my attention: this one from the New York Times describing the White House influence on the NPR, which includes unnamed officials revealing back-channel negotiations with European allies debating whether or not to withdraw the approximately 200 B-61 air-deliverable “gravity bombs” stored in six countries; and this story which indicates that the U.S. may decide to retire the Nuclear Tomahawk Land-Attack Cruise Missile (TLAM-N), which the Japanese have considered a vital U.S. weapon for ensuring their security against both China and North Korea.

These developments are troubling to say the least, and strategically foolish to take at this time (even if one believes they need to be taken eventually). First, the proposal to withdraw our tactical nuclear weapons from our NATO allies is not a wise move because the U.S. would essentially get nothing for it. According to this Guardian story, officials in “Benelux,” Norway, and Germany are planning to call for the removal of U.S. tactical nukes from Europe (no advocacy for withdrawing them from the Italians or Turks…yet). Though most recognize that these nukes, only deliverable via fighter-bombers (think F-16s, the new F-35, etc.), are of limited military utility, their political importance has been their status as a cornerstone of the Trans-Atlantic Alliance for over fifty years. To remove them would mean that the U.S. would be perceived as having even less reason to retaliate against an ally struck by a biological attack or ballistic missiles. The diminished footprint in Western Europe is sure to reflect the lessened importance the Obama administration attaches to such important allies as the UK (see here).

That being said, if the Europeans don’t want them (and more importantly, their political and military officials), the U.S. cannot force them down their throat. A more comprehensive strategy to “de-nuclearize” Europe would be more effective in satisfying Europeans while upholding the Trans-Atlantic alliance. Separate from the START accord, the U.S. could propose to Russia a treaty to reduce, limit, or open for inspection arsenals of tactical nuclear weapons, in exchange for the U.S. withdrawing some or all of its nukes from Europe. This has long been a Russian talking point, and the fig leaf it has hid behind for its maintenance of 3-4,000 tac-nukes. If the U.S. (in consultation with European allies) offers to return these to domestic bases, the onus for weapons reductions and increased transparency will be on Moscow. However, it is doubtful whether the Turks would agree to evicting U.S. nukes or if the other Central and Eastern European allies in NATO would consent to removing most or all U.S. tactical nukes from the continent.

Therefore current proposals to unilaterally withdraw all U.S. tactical nuclear weapons from Europe are naive. The U.S. would get nothing for a significant concession. Better to maintain them as additional leverage when the time comes to try to negotiate a reduction in Moscow’s 10-1 advantage in these weapons.


Turning to the Pacific theater, the issue of TLAM-N retirement is more subtle and bilateral. These nuclear cruise missiles, designed for deployment on attack submarines, have been mostly kept in storage since the end of the Cold War (although secret deployments are highly likely). Nonetheless, their mere presence and the latent capability the U.S. possesses with them have reassured Japan as it faces mounting threats to its security from Beijing and Pyongyang. In fact, Tokyo communicated to the Strategic Posture (Perry-Schlesinger) Commission that the “credibility of the U.S. extended deterrent depends on its specific capabilities to hold a wide variety of targets at risk, and to deploy forces in a way that is either visible or stealthy, as circumstances may demand.”

The Commission went on to find that “In Asia, extended deterrence relies heavily on the deployment of nuclear cruise missiles on some Los Angeles class attack submarines. This [TLAM-N] capability will be retired in 2013 unless steps are taken to maintain it. U.S. allies in Asia are not integrated in the same way into nuclear planning and have not been asked to make commitments to delivery systems. In our work as a Commission it has become clear that some U.S. allies in Asia would be very concerned by TLAM-N retirement.” Therefore any decisions to retire this unique capability should not be made absent consultation with Japan and an assessment of alternative ways to reassure Japan that the U.S. extended deterrent will guarantee its security. It is unlikely that the NPR will do this. If the U.S. does not want to raise Tokyo’s insecurity to the point it develops its own deterrent, it must take its commitments to extended deterrence seriously.

Tactical nuclear weapons have returned to the forefront of the nuclear posture debate. This time it concerns their very existence in U.S. arsenals – the TLAM-Ns will be retired and the B-61s will lose their purpose (not much reason to maintain tactical gravity bombs for fighter aircraft in the continental U.S.). Nuclear disarmament and Global Zero advocates have loudly claimed that they are not in favor of the U.S. unilaterally disarming. If they want that claim to be believable, they should communicate to President Obama that unilateral reductions in tactical nuclear weapons is unwise, if for no other reason than to maintain levers for future disarmament. Others, including defense hawks, can just oppose such policies on the demerits of their naivete.

The CTBT Revisited: Has Anything Really Changed?

The Comprehensive Test Ban Treaty (CTBT), an agreement which would ban all nuclear tests, may soon be revived from its purgatory in the Senate. It was signed by President Clinton in 1996 and rejected by the Senate in October 1999. The arguments that denied ratification by a 19 vote margin still ring true today. In his Prague speech, however, President Obama called for prompt U.S. ratification of the treaty. He is expected to do the same at the UN later this month.

In rejecting the CTBT, Senate opponents listed several concerns that motivated their decision. They believed the CTBT was unverifiable and that others nations could easily cheat; the ability to enforce the treaty was dubious; the U.S. nuclear stockpile would not be as safe or reliable in the absence of testing; and the benefit to nuclear nonproliferation was minimal.

Ten years later, many of these concerns are still relevant. The issue of verification has been improved but not settled. The CTBT Organization has set up a network of 228 monitoring stations around the world, but significant gaps still exist. There are no stations in India or North Korea, and only one in Pakistan and Turkey. Sixty-one stations detected North Korea’s nuclear test in May 2009, but none detected radioactive gases to corroborate the seismic data. If North Korea was able to conceal such radiation, there is no reason to believe China or Russia could not as well.

As the continuing crises with North Korea and Iran illustrate, enforcing treaty obligations or punishing rule-breakers is not always effective. It is often, in fact, completely ineffective due to a lack of international cooperation. If a nuclear test were detected in Pakistan, India, or China, what would happen next? If the record with Pyongyang or Tehran is any indicator, the violating state would take some rhetorical heat and little more than a toothless UN Security Council resolution (if that). The CTBT will not immediately change other states’ policies.

The last decade has not been kind to the U.S. nuclear weapons arsenal. Though the Stockpile Stewardship Program has successfully replaced older components, confidence in reliability has declined as the warheads age. Secretary of Defense Robert Gates has stated that a credible U.S. deterrent cannot be maintained without testing or modernizing U.S. nuclear weapons. If modernization is not pursued, many experts believe testing will be needed to guarantee the weapons’ reliability.

Most significantly, the treaty’s perceived benefits toward enhancing nuclear nonproliferation are still debatable. Pro-CTBT voices have made several valid claims to consider. They argue that without the CTBT the nuclear arms race will continue, especially in Asia, with more states hedging their capabilities to be able to assemble a nuclear weapon quickly. Treaty advocates are quick to point out that the U.S. has already received a benefit for pursuing ratification – the indefinite extension of the Nuclear Nonproliferation Treaty (NPT) in 1995. The NPT, which divides the world into five nuclear weapon states (NWS) and the rest as non-NWS, is up for review in May 2010. The non-NWS are likely going to insist on CTBT ratification in exchange for nonproliferation cooperation.

These arguments still do not explain how the CTBT will be good for nonproliferation. For one, the existence of a nuclear arms race (outside India and Pakistan) is suspect, given the fact that the U.S. and Russia are reducing their nuclear stockpiles. Nuclear hedging is a problem to be tackled by IAEA monitoring; not by attempting to ban nuclear tests (the NPT already does this for non-NWS). Though the non-nuclears may insist on entry into force of the CTBT, there is little reason to believe they will take tougher actions on Pyongyang and Tehran once the U.S. ratifies it. If unilaterally and bilaterally reducing nuclear arsenals and not testing for 17 years have done nothing to convince non-NWS of U.S. leadership, why will the CTBT?

The CTBT is simply not in the U.S. national interest. The U.S. would not be guaranteed a seat on the Executive Council, which geographically would be unfriendly to Washington. Since it requires North Korean, Pakistani, and Egyptian ratification (to name a few), the U.S. would be binding itself to a treaty unlikely to ever enter into force. Though there would be a growing ability to detect nuclear tests, there would be no effective way to enforce the treaty. The U.S. stockpile would continue to atrophy as explosive testing for reliability would be prohibited, which could spur proliferation. The CTBT needs to be rewritten to mitigate these drawbacks, not “immediately and aggressively”[xi] brought before the U.S. Senate.

Mr. Obama Goes to Moscow

President Barack Obama and Russian President Dmitry Medvedev are meeting in Moscow to discuss a successor to the soon-to-expire Strategic Arms Reduction Treaty (START). On the table for consideration (according to U.S. and/or Russian officials) are levels of deployed and stockpiled strategic nuclear warheads, strategic delivery systems (intercontinental ballistic missiles, or ICBMs, and bombers), and missile defense. Off the table are nonstrategic nuclear weapons, which the Russians hold in abundance.

Truly understanding the situation between Washington and Moscow requires a brief look at the numbers:
U.S. - 2,200 strategic nukes deployed (~2,500 reserve)
U.S. - ~1,000 ICBMs, SLBMs, and strategic bombers
U.S. - 400-500 tactical nukes
Russia - 2,700 strategic nukes deployed (unknown thousands in reserve)
Russia - ~650 ICBMs, SLBMs, and strategic bombers
Russia - 3,000-5,000 tactical nukes

In terms of strategic delivery systems, the U.S. still has decades before most of its systems will need replaced, while many Russian systems will reach the end of their service lives within the next decade, reducing their numbers to around 330.

The Obama Administration, in its rush to conclude the START follow-on by the current treaty’s expiration date on December 5th, is therefore playing into the Russians’ hands. By pushing for deep warhead cuts (the Russians will not go below 1,500 deployed) and considering a further reduction in the permitted number of strategic delivery vehicles, U.S. negotiators are essentially getting nothing for something. Since the Russians will have to eliminate many of their aging warheads, missiles, and bombers with or without an arms control treaty, they are trying to maintain parity with the United States through a new START accord. In return, the U.S. is getting something it would have gotten without having to reduce the survivability and flexibility of its nuclear arsenal.

Until recently, the Obama Administration was seemingly giving credence to Russian objections to a third missile defense site in Central Europe. Even former Secretary of Defense (and nuclear abolitionist) William Perry (D) stated in House testimony that trading missile defense for Russian promises was absolutely unreasonable. The president’s special assistant, Michael McFaul, stated last week the U.S. was “not going to reassure or give or trade anything with the Russians regarding NATO expansion or missile defense.” This is a step in the right direction. Tying defensive conventional systems to offensive nuclear systems, which President Medvedev is still insisting on, is a relic of the Cold War “mutually assured destruction” thinking.

Therefore, the U.S. approach to the START follow-on has been fundamentally flawed. By agreeing not to include nonstrategic nuclear weapons in the limits, the U.S. allowed Russia to maintain its biggest geopolitical advantage. Many experts believe it is these “battlefield” nuke stockpiles that will be the likely source of any future nuclear terrorism or nuclear use by a state (Russia explicitly states they would be used to “de-escalate” an invasion of their homeland). Furthermore, once U.S. warhead and delivery system levels have been drastically reduced, Washington will little leverage to urge Moscow to reduce its tactical nukes.

The arms control process is also misguided in the link some are attempting to make between a new START and “global zero,” the nuclear abolitionist movement. The bipartisan Strategic Posture Commission determined that complete nuclear disarmament required a “fundamental transformation of the world political order.” Guiding a new treaty along what optimists consider a decades-long goal is a recipe for miscalculation and bad decisions. The Obama Administration needs to take a step back, assess U.S. interests over the long term, and proceed with a modest START follow-on from there. Idealism is one thing. Dealing with the Russians about nuclear weapons is entirely different.
