4 mar 1955 ano - Peaceful coexistence

Descrição:

Peaceful coexistence (1955–1960) — period in Soviet-American relations marked by less tension and by personal diplomacy between Khrushchev and Eisenhower; the two leaders recognized that, in a nuclear age, competition between their nations must be peaceful. This thaw in the Cold War was ended by the U-2 spy plane incident over the Soviet Union in 1960.
