The accurate outcome of the Cuban Missile Crisis was:
A. The tension between the U.S. and the Soviet Union decreased.
During the Cuban Missile Crisis in 1962, tensions between the United States and the Soviet Union were at an all-time high due to the placement of Soviet missiles in Cuba. However, through diplomatic negotiations and a series of backchannel communications between President Kennedy and Premier Khrushchev, a resolution was reached. The crisis ended with the Soviet Union agreeing to remove its missiles from Cuba, and the U.S. promising not to invade Cuba. This led to a decrease in tensions between the two superpowers and a realization of the need for better communication to avoid such a crisis in the future.
