All of these events: Bay of Pigs invasion, Completion of the Berlin Wall and the Cuban Missile Crisis, happened during the presidency of John F. Kennedy.

Explanation:

The conflict with the Soviet Union began at the very end of the Second World War, as both the United States and the Soviet Union sought to superimpose their own political systems in the now weakened European nations, with the exception of England. A race for control and power began. The United States, fought the advancement of communism, and the Soviet Union, through both economical and military strategies. Many U.S., presidents faced these issues, but the one who had to face the reality of a possible third world war, was John F. Kennedy, when he took office in the 1960´s. He received from Eisenhower the strategic idea of training and using exiled Cubans to invade their nation, in the Bay of Pigs Invasion, which was a disaster, then, the fulfillment of Nikita Kruschev´s promise to block off the East part of Berlin by the completion of the Berlin Wall, and finally, he also had to face the Cuban Missile Crisis, when Kruschev agreed with the Cuban government to supply nuclear missiles. Kennedy responded by initiating a naval blockade on the island and warned Kruschev that if anything happened, there would be war between the two nations. Kruschev responded to the demands of Kennedy and removed the nuclear missile sites from Cuba in exchange for an agreement with the U.S.
