The Cuban Missile Crisis was a 13-day confrontation between
the governments of the United States and the Soviet Union,
when American deployments of nuclear missiles in Italy and
Turkey were matched by Soviet deployments of nuclear missiles
in Cuba.

The crisis lasted from 16 to 28 October 1962. The confrontation
is widely considered the closest the Cold War came to escalating
into full-scale nuclear war.

the time between the two Cold War antagonists.
