Will Japan Try to Save the INF Treaty?

, China project manager and senior analyst

US President Ronald Reagan and Japanese Prime Minister Yasuhiro Nakasone meet at Camp David in 1986.

President Trump said he plans to withdraw from the Intermediate Nuclear Forces (INF) Treaty. US National Security Advisor John Bolton implied the government of Japan already agreed.

Not long after Bolton’s statement, Foreign Minister Taro Kono told reporters the Abe government needed to discuss the fate of the treaty with US officials before commenting. Six days later US Deputy Assistant Secretary of State for Arms Control Tom DiNanno and Deputy Assistant Secretary for East Asia Marc Knapper arrived in Tokyo for a three-day dialog on US extended deterrence guarantees for Japan. The fate of the INF treaty was on their agenda. What did Japanese officials tell the Trump administration? Read more >

China and the INF Treaty

, China project manager and senior analyst

Some US analysts and officials argue the United States should withdraw from the Intermediate Nuclear Forces (INF) Treaty because it prevents the United States from responding to China’s deployed short- and intermediate-range ground-based missiles. They argue the United States should abandon a bilateral arms control agreement intended to prevent Russia from threatening Western Europe to make it easier for the United States to threaten China.

These are dubious arguments. The US nuclear arsenal is more than 10 times larger than China’s and Chinese military strategists already believe the United States possesses conventional military superiority. Read more >

No, Space-Based Missile Defense Will Not Cost Only $20 Billion. (Spoiler: That’s only the launch costs.)

, senior scientist

Space-based missile defense is a terrible idea. It is expensive and straightforwardly defeated, and it is dangerous and destabilizing. (If you haven’t watched it, please do take a look at this video and web feature UCS just produced. It helps to see these arguments visually.)

But knowledgeable people say it’s not so expensive!

At a recent event hosted by the Missile Defense Advocacy, Under Secretary of Defense for Research and Engineering Mike Griffin calculated the cost to “put up” an interceptor layer. Given how Griffin talked about it, you may be forgiven for thinking he means this is the full cost of a space-based missile defense system—rather than just the cost of launching the interceptors into space.

Opposition to Trump’s New Low-Yield Nuclear Warhead

, Washington representative and senior analyst

And the “consensus” on rebuilding the US nuclear stockpile

The Trump administration’s program to deploy a new, low-yield variant of the W76 warhead carried by U.S. submarine-launched ballistic missiles has faced relatively strong opposition in Congress, with almost all Democrats and several Republicans supporting legislation to eliminate or curb the program.

Trump Wants a New Low-Yield Nuclear Weapon. But the US Has Plenty Already.

, analyst

The Trump administration’s Nuclear Posture Review (NPR), released in February of this year, calls attention to the composition of the US nuclear arsenal and its adequacy as a deterrent. The NPR calls for a new lower-yield submarine-launched nuclear warhead, arguing that it is needed to “counter any mistaken perception of an exploitable ‘gap’ in U.S. regional deterrence capabilities.” We decided to put together the chart in Fig. 1 to illustrate the range of nuclear weapons already available in the US arsenal.

One thing that this visual immediately makes clear is that it would be difficult to perceive any real gap in US capabilities—the existing arsenal certainly does not lack for nuclear options for any occasion. Read more >
