On 8 September 1958, the United States sent a note to the Soviet Union calling for a Soviet answer to US proposals for a "study of the technical aspects of safeguards against the possibility of surprise attack." One week later the Soviets agreed to participate and suggested that the talks begin in Geneva on 10 November 1958. President Eisenhower was also attempting to per- suade the Soviet Union to begin talks aimed at eliminating the atmo- spheric testing of nuclear weapons. These efforts began with a 22 August 1958 offer to suspend US nuclear tests for one year on the condition that the Soviet Union also refrain from further tests and join in negotiations.

Four days later, Soviet troops began harassing US Army truck convoys on the highways leading from West Germany to West Berlin. Although this new Berlin crisis never became as threatening as the blockade of 1948-49, President Eisenhower wished to avoid any actions that would provoke the Soviets. Tension over West Berlin was, therefore, an additional reason for continuing to keep the U-2 away from the Soviet Bloc.m2 CONCERNS ABOUT SOVIET COUNTERMEASURES AGAINST THE U-2 Another reason for President Eisenhower's growing reluctance to au- thorize flights over the Soviet Union may have been concern that the Soviets were developing countermeasures that would enable them to Ambrose.
