Which two key events in the Cold War happened before 1970?

1. The Berlin Blockade and Airlift (1948-1949): This event marked the first major crisis of the Cold War, with the Soviet Union blockading West Berlin in an attempt to force the Allies out of the city. The Allies responded by carrying out a massive airlift to supply the city, ultimately leading to the blockade being lifted.

2. The Cuban Missile Crisis (1962): This event brought the world to the brink of nuclear war, as the United States and the Soviet Union engaged in a tense standoff over the presence of Soviet missiles in Cuba. After a 13-day standoff, the two superpowers reached a resolution that involved the removal of the missiles from Cuba and a promise by the United States not to invade the island.
