The Cold War event that happened last was the ending of the Vietnam War.

Explanation:

1- The Korean War, a confrontation between North Korea (supported by communist countries) and South Korea (supported by America), occurred between June 25, 1950 and July 27, 1953. This confrontation ended in a status quo, with both nations separated by a demilitarized zone.

2- Sputnik was the first artificial satellite in history, launched by the Soviet Union on October 4, 1957.

3- The Cuban Missile Crisis took place during October 1962, when Soviet missiles were located in Cuba by American planes, unleashing a diplomatic tension that threatened to unleash a nuclear war between the two superpowers. Finally, on October 28, 1962, the United States and the USSR reached an agreement that prevented the confrontation, which implied the dismantling of the missile bases in Cuba.

4- The Vietnam War was an armed conflict that took place between 1955 and 1975 in Vietnam and in the borders of neighboring countries (Cambodia and Laos). This war faced North Vietnam, communist, against South Vietnam, democratic and supported by the United States. This war ended in 1975 with the communist conquest of South Vietnam, and implied the first American defeat in a war in its history.
