An article in the New York Times made the rounds last week, asserting that the new modification (“mod”) of the B61 nuclear gravity bomb was of a lower yield than its predecessors, and arguing that lower-yield, precision weapons are destabilizing to nuclear strategy and that their relatively limited destructive capabilities in turn render them more likely to be used than the multi-megaton, Cold War-era city-busters. It was also proclaimed that this was the death knell for the Obama Administration’s disarmament and arms control efforts, and represented a “new arms race” between nuclear powers.
The argument is well-intentioned, but misguided.
The article quotes the usual suspects – James Cartwright, Andrew Weber, William Perry – and offers some assertions that are patently false on their face.
David Sanger and William Broad, the authors of this piece, focus solely on US weapons development and policy in a bubble, ignoring the larger context of the world in which nuclear weapons exist. As they and their interview subjects characterize it, the United States is the one upsetting the nuclear balance:
Already there are hints of a new arms race. Russia called the B61 tests “irresponsible” and “openly provocative.” China is said to be especially worried about plans for a nuclear-tipped cruise missile. And North Korea last week defended its pursuit of a hydrogen bomb by describing the “ever-growing nuclear threat” from the United States.
This, of course, ignores the fact that Russia has violated the Intermediate Nuclear Forces Treaty, China has refused to enter into any arms control arrangements and is busy expanding its own arsenal (including the production of new nuclear warheads and delivery vehicles; the former something that the United States still will not do), and North Korea has rejected carrot and stick approaches alike dating back several decades. If the Presidential Nuclear Initiatives in the aftermath of the Cold War – or the past 30 years of sanctions – were insufficient to dissuade Pyongyang from nuclear proliferation, it’s hard to envision what would.
