A)the Cold War
Nikita Khrushchev (1894–1971) was the Soviet Union's leader from 1958 to 1964, during the Cold War's height. Though he generally maintained a policy of peaceful coexistence with the West, the Cuban Missile Crisis erupted when he deployed nuclear missiles 90 miles from Florida. At home, he launched a process of "de-Stalinization" that reduced the repressive nature of Soviet society. Khrushchev, on the other hand, could be authoritarian in his own right, crushing an uprising in Hungary and supporting the Berlin Wall's erection. Known for his flamboyant remarks, he famously removed and displayed his shoe at the United Nations.
