To answer your question accurately, I would need to know which specific event you are referring to. However, during the Cold War period, notable leaders included President John F. Kennedy for the U.S. and Premier Nikita Khrushchev for the USSR during the Cuban Missile Crisis in 1962. Later, President Ronald Reagan led the U.S. while Mikhail Gorbachev was the General Secretary of the Communist Party in the USSR during the late 1980s, a pivotal time in the Cold War's conclusion.
