The outrightly suicidal strategy of nations protecting themselves from nuclear (or, in more recent days, chemical or biological) attack by preparing enough weapons to reduce the attacking country to rubble even as they are themselves wiped out.

Basically, if you're going to be screwed over, make sure the rest of the world is, too.

A Cold War idea that neither the U.S. or the U.S.S.R. would use nuclear weapons on the other, knowing attack would lead to a mutually devatating counterattack.
