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 >

To no one’s surprise, both the administration and Congress increased funding for the NNSA and, in particular, for its nuclear weapons work. Read more >

China Not an Obstacle to US Summit with North Korea

, China project manager and senior analyst

Last fall, as North Korea raced to demonstrate it could strike the United States with a nuclear-armed missile, the Chinese government acceded to strict international economic sanctions it previously resisted. This spring, after North Korea declared it had achieved its goal and would stop further testing, the Chinese government acceded to North Korean requests for greater engagement, including high-profile meetings between Xi Jinping and Kim Jong-un.

President Trump, along with many US officials and observers, praised China’s willingness to sign on to tougher sanctions. But they greeted China’s positive response to North Korea’s testing freeze with a mix of skepticism and suspicion. Trump suggested his Chinese counterpart was playing geopolitical poker with the summit in Singapore. US observers wondered whether China felt threatened by the summit and intentionally undermined it.

That’s unlikely. Read more >
