U.S. and Soviet leaders met at the 1955 Geneva Summit, the first such summit since the 1945 Potsdam Conference. No progress was made on major issues; the two sides had major differences on German policy, and the Soviets dismissed Eisenhower's 'Open Skies' proposal. Despite the lack of agreement on substantive issues, the conference marked the start of a minor thaw in Cold War relations. Kruschev toured the United States in 1959, and he and Eisenhower conducted high-level talks regarding nuclear disarmament and the status of Berlin. Eisenhower wanted limits on nuclear weapons testing and on-site inspections of nuclear weapons, while Kruschev initially sought the total elimination of nuclear arsenals.
