The stated mission of the November 1955 Geneva summit was to reduce international tensions between the leaders of “Big Four” nations France, Great Britain, USA and USSR.
The world leaders discussed issues on security, armaments, German unification, and stronger East-West relationships.
Premier Khrushchev was willing to allow a united Germany providing it was neutral, but the recent entrance of West Germany into NATO made the situation increasingly complicated.
The Soviet delegation stated that if peace were the only North Atlantic Treaty Organization objective, there should be no objection to the USSR joining. CIA Director Allan Dulles, however, advised President Eisenhower to refuse this proposal and the subject was neglected during the rest of the summit.
The 1955 Big Four Conference in Geneva created an era of renewed optimism in cold war relationships that was soon disrupted by the Suez Crisis in 1956.
