Who was Joseph McCarthy and Nikita Khrushchev?

Joseph McCarthy was a U.S. Senator from Wisconsin known for his role in the Red Scare during the early 1950s, where he led aggressive investigations and hearings aimed at exposing alleged communists in government and other sectors, a period now often associated with anti-communist hysteria. Nikita Khrushchev was the leader of the Soviet Union from 1953 to 1964, notable for his policy of de-Stalinization, attempts at reforming the Soviet economy, and his confrontational stance during the Cold War, including events like the Cuban Missile Crisis. Both figures played significant roles in shaping the political landscape of the Cold War era.
