Material aid and reverse Lend-Lease

A tenth-anniversary summary cites President Truman's January 1950 report before listing aircraft, tanks, vehicles, explosives, metals, and millions of pairs of boots sent to the Soviet Union. It attributes to wartime Under Secretary of State Sumner Welles the claim that Stalin told the Tehran Conference the war would have been lost without American production, and it notes British lives lost transporting supplies. The figures show that Lend-Lease supported mobility and sustainment as well as headline combat equipment. The Soviet Union's reverse contribution is described as limited, while the British Empire supplied nearly 90 percent of the cited reverse Lend-Lease to American forces. British and Commonwealth contributions included locally supplied war material, radar knowledge, and the Bailey bridge. The flows were unequal, but coalition exchange ran in both directions.
