In Cuba, a charismatic young leftist named Fidel Castro leads his guerilla forces triumphantly into Havana, toppling the government of Fulgencio Batista. While most Cubans initially celebrate Castro's victory over the unpopular, corrupt Batista, Americans fear that Castro will establish a Soviet-friendly regime just 90 miles off the Florida coast.

Even while demonstrating his commitment to the Cold War by promising that he will not shrink from defending freedom, he also promises to be open to cooperation with the Soviet Union in the interest of peace and arms control. "Let us never negotiate out of fear," he says. "But let us never fear to negotiate. Let both sides explore what problems unite us instead of belaboring those problems which divide us."
Mar 13, 1961
President John F. Kennedy launches the Alliance for Progress, a massive program of economic aid for the Western Hemisphere akin to the earlier Marshall Plan for Western Europe.

American and Soviet tanks face off for two days at Checkpoint Charlie, one of the few border crossings remaining between East and West Berlin following East Germany's closure of the border.

After one of these tests, Soviet tanks menacingly approach the border. Clay calls out his tanks to meet them. The confrontation is only resolved when Soviet Premier Nikita Khrushchev and President John F. Kennedy negotiate a deal: the Soviet tanks will back down if Kennedy will not protest the construction of the Berlin Wall.

The Cuban Missile Crisis ends after President Kennedy and Premier Khrushchev reach a secret agreement: the Soviet Union agrees to remove its missiles from Cuba if the Americans will remove its own Jupiter missiles from Turkey (which is about as far from the USSR as Cuba is from the U.S.).

Dec 19, 1964
Defense Secretary Robert McNamara develops the idea of Mutual Assured Destruction, which holds that in a world in which both the U.S. and USSR possess enough nuclear weapons to wipe each other off the map, both sides' fears of nuclear retaliation will prevent either from ever using the weapons for aggressive purposes. Thus nuclear weapons are the best deterrent against nuclear war. Although critics decry McNamara's nuclear "balance of terror" policy as mad (MAD, conveniently, is the acronym for Mutual Assured Destruction), McNamara believes his policy will help maintain a stable nuclear world.

West and East Germany sign the Treaty for the Basis of Relations (also known as the Basic Treaty), which gives East Germany de facto recognition of its statehood and borders though not de jure recognition. This means that while West German leader Willy Brandt is willing to recognize that East Germany operates as a sovereign state in practice, he is not willing to legally define East Germany as a separate from the German nation. Brandt adopts this stance because he hopes for the eventual reunification of Germany. This distinction between de facto and de jure recognition plays out in East and West Germany's exchange of permanent representatives rather than ambassadors.
