“Let me be crystal clear: There is no such thing as ‘limited use’ nuclear weapons, and for a Pentagon advisory board to promote their development is absolutely unacceptable. This is even more problematic given President Trump’s comments in support of a nuclear arms race.
As Deputy Defense Secretary Robert Work testified in 2015, ‘Anyone who thinks they can control escalation through the use of nuclear weapons is literally playing with fire. Escalation is escalation, and nuclear use would be the ultimate escalation.’
Nuclear weapons present us with a paradox: We spend billions of dollars building and maintaining them in the hope that we never have to use them. The sole purpose of nuclear weapons must be to deter their use by others. Designing new low-yield nuclear weapons for limited strikes dangerously lowers the threshold for their use. Such a recommendation undermines the stability created by deterrence, thereby increasing the likelihood of sparking an unwinnable nuclear war.”
