ABSTRACT
The Anglo-American observers believe that Western supplies to the USSR were decisive for the Soviet war effort at the time, and it is possible that Anglo-American intelligence assessments of Soviet military-economic strength had some implications for the delivery of aid to the USSR. Considering the lingering insecurity concerning Soviet staying power, material aid was of the utmost importance from the Allied perspective. Even when the war ended in May 1945 aid was still coming into Soviet ports from the United States, and ended only when the war with Japan was over. The state of Soviet military-economic strength was under investigation with the intent of evaluation the need of aid, even during the summer of 1941, and some of the assessments was even sent to Roosevelt personally. The Roosevelt administration wanted to avoid a Soviet collapse at any cost, and even sent equipment to the Soviets that delayed the build-up of US forces.
