The article critically analyses the economical and political inconsistency of the assessment of the decisive factor of the Anglo-American aid to the USSR during the years of the World War II against Hitlerism. Based on the economical parameters, the author shows a noteworthy political role of the Soviet leadership in building the national military industrial complex in the shortest time. Foreign politicians have been consistently trying to diminish the role the Soviet Union played while achieving the common victory of the anti-Hitler coalition countries over Nazi Germany. Starting since 1945, after effectively declaring “cold war” against the Soviet Union, our enemies have been using falsified data and documents to create a distorted vision of the operations conducted by the Red Army on the Eastern front in the public eye (“filled up Germans with corpses”). Not infrequently, the foundation of such “historical research” contains objective data which is not denied by national historians - presence in the Red Army of a vast number of American trucks and cross-country vehicles, significant role of canned stewed meat, dry milk, and antibiotics provided by the US. However, the true subtext of our ill-wishers’ works is aimed at diminishing the intellectual potential of the Russian people, an urge to present them as dim-witted executors of the leadership’s orders. Along with denying the decisive factor of the Soviet Army’s offensive operations in the defeat of the Wehrmacht, they put in doubt the Soviet contemporary science of warfare, technology, and innovations in the military industry. This article attempts to show the greatness of the labor heroism of Soviet scientists, engineers, and workers.
