Why a recovered Soviet Union could still produce a Cold War

If the Soviet Union survived, recovered, and returned to its historical position, would the Cold War still happen?

Probably yes; a successor committee could still harden into another dictatorship.

A Soviet Union that recovered to its historical strength could still enter a Cold War. Stalin's replacement should not be assumed to govern more benignly. An initial committee or collective leadership was plausible after a succession crisis, but that arrangement could readily end with another dictator consolidating power.
