Basically a Mexican standoff between prominent countries that possess nuclear weapons and have different polictical agendas. Causes the entire world to be gripped in a sort of doomsday fatalism. Also results in peace talks to boil down to a pissing match in which each side takes a "I'll-throw-down-my-gun-if-you-throw-down-your-gun-first" attitude.
In "Beneath the Planet of the Apes" the apes may have survived if they had thier own nukes. The mutant humans wouldn't have used thier nuke because of fear of mutually assured destruction. Which didn't matter anyway, because they all ended up dead, like a bunch of pork rinds.

A term expressing an expectation of reciprocity. If event A happens, then event B will certainly follow. Most commonly used in the phrase "mutually assured destruction," which posits that the best defense against a nuclear-based attack is the threat of a "mutually assured" retaliatory nuclear-based attack...although the term can be applied to events less earth-shakingly catastrophic.
"If I go down on you, it damn well better be mutually assured that you'll be sucking my cock afterwards."
