Nikita Khrushchev – Eisenhower sought a thaw in the Cold War through negotiations with the new Soviet leaders who came to power after Stalin’s death in 1953. However, the new Soviet premier Khrushchev rudely rejected Ike’s ideas for peace at the Geneva summit conference in 1955. When Ike called for “open skies” over both the USSR and USA to prevent either side from miscalculating the others military intentions, Khrushchev bluntly rejected. Khrushchev’s denouncement of Stalin’s totalitarian dictatorship, and the end of Soviet occupation of Austria, both caused a thaw in the Cold War, however the Hungarian uprising reversed this progress.
