The Ukraine Nuclear Delusion

GENEVA – An argument now widely heard is that Ukraine would not be in the trouble it is in had it retained its substantial stockpile of nuclear weapons at the end of the Cold War. This has dangerous policy implications, and must not go unchallenged.

Despite its superficial plausibility, the argument does not withstand scrutiny against the available evidence about how states behave. Nuclear weapons are simply not the effective deterrent that most people think, whether the context is deterring war between large nuclear-armed powers or protecting weaker states against conventional attack.
