The soviet union and the united states nearly went to war with each other in 1962 when the united states discovered soviet missiles on the island of cuba this event, called the cuban missile crisis, was resolved peacefully after sever days of negotiations between u. s. and soviet leaders.

I dont see the question here :/ are you asking how else did they prevent the Cuban Missile Crisis??
-Navy created a blockade, cuting off the Soviet Union to make any contact with cuba

On October 22, President Kennedy spoke to the nation about the crisis in a televised address. No one was sure h ow Soviet leader Nikita Khrushchev would respond to the naval blockade and US demands. ... In 1963, there were signs of a lessening of tensions between the Soviet Union and the United States.
