At a Geneva Conference meeting with Soviet Premier Nikolai Bulganin in 1955, U.S. President Eisenhower proposed that the United States and Soviet Union conduct surveillance overflights of each other's territory to reassure each country that the other was not preparing to attack. The fears and suspicions of the Cold War led Soviet General Secretary Nikita Khrushchev to reject Eisenhower's proposal, known as the Open Skies proposal.
