CUBAN MISSLE CRISIS
October 1962
Canadian and America battle ships were prepared to fire on the Soviet ships if they tried to run the blockade.
"The Cuban missile crisis marked the climax of an acutely antagonistic period in U.S.-Soviet relations. The crisis also marked the closest point that the world had ever come to global nuclear war. It is generally believed that the Soviets’ humiliation in Cuba played an important part in Khrushchev’s fall from power in October 1964 and in the Soviet Union’s determination to achieve, at the least, a nuclear parity with the United States."
