Khrushchev referred to the U-2 incident to the Supreme Soviet as an act of American aggression. This incident cancelled the possibility of the 2 superpowers meeting is Paris at a summit meeting or any other time soon.

Allowed for Bay of Pigs invasion because he was told that Cuban revolutionaries would aid the American troops against Castro and start a revolution against communism. However, Kennedy limited the amount of troops and aircraft which could have ultimately been the cause of the mission's failure. The Bay of Pigs invasion increased the tension between the 2 superpowers

Increased the number of military advisers in Vietnam.

Claimed that the U-2 spy jet was not a spy but was lost and accidentally flew into Soviet territory. This lie created more tension

Korea: The People´s Republic of China sent hundreds of thousands of troops, aided by the Soviet Union, to push the UN troops away from the Yalu river, near China.

Vietnam: No Chinese boots on the ground but the Chinese Communist Party provided arms, military training, and supplies to help Communist North defeat Capitalist South Vietnam

Korea was split and is to this day split between communist and capitalist because an armistice was signed between North and South Korea (they are still technically at war). The Vietnam War resulted in communist victory after U.S withdrew and South Vietnam fell to the communist-run Democratic Republic of Vietnam in 1975, the current government of a united Vietnam.

In Korea, 5 million people, 10% of the pre-war population, were killed. In Vietnam. In Vietnam, 1.3 million people died.

The Vietnam War started as a Civil War across Vietnam with French involvement before U.S. involvement but the Korean War started when North Korean troops invaded South Korea. The U.N. got involved in Korea stating that the attack by North Korea was an act of Soviet aggression and expansion.

After Japanese occupation in WW2, Korea was split at the 38th parallel between the U.S. and the U.S.S.R. Anyone above the 38th parallel would be subject to communist dictatorship under Kim Il-sung, appointed by the Soviets, while everyone below the border would be subject to capitalist dictatorship.

The North Korean attack was a well thought out and well prepared surprise attack on the unsuspected South. The North would have pushed further south and most likely would have won the war if not for the involvement of the UN. The UN only got involved because they saw the invasion from North Korea as Soviet expansion., which goes against the American policy of containment. The Americans coined the term ¨Domino effect¨ to spread fear in America of the possibility of all of Asia falling to communism.

Khrushchev´s public global justification for allowing missiles in Cuba was that the missiles were in response to the American Bay of Pigs invasion of Cuba. The sneaking in of these missiles in Cuba sparked widespread fear in the U.S. in what is known here as the Cuban Missile Crisis. Additionally, the missiles gave the USSR some power/influence.

Khrushchev preferred to limit involvement of the USSR in the Vietnam War while the U.S.A. stayed on the soil and in the skies of Vietnam for almost 20 years, from 1955 to 1973. This lack of Soviet involvement resulted in less tension between the nations as the 2 nations were much less likely to encounter each other in combat with less involvement from 1 side.
