During World War II the United States shipped an enormous amount of aid to the Soviet Union through the Lend-Lease program. The significance of this aid to the Soviet war effort has long been debated. During the Cold War, the Russians minimized its impact and the West exaggerated it. While it is obviously impossible to know what would have happened without the aid, it is clear that Lend-Lease came too late to be the decisive factor in the Soviet victory. But it is equally clear that when aid began to arrive on a massive scale, it significantly increased the speed with which the German Army was pushed out of the Soviet Union. Without Lend-Lease, the Soviet people would have had to make even greater sacrifices and would have suffered even more deaths.
The American Lend-Lease aid program was passed by the United States Congress in March of 1941 originally to support the war effort in Great Britain. American public and congressional opinion at first resisted the idea of extending the aid to the Soviet Union. Many Americans shared the views of Senator Harry S. Truman of Missouri, who argued, “If we see that Germany is winning, we ought to help Russia. If Russia is winning, we ought to help Germany.” But aid was offered to the Soviet Union in October 1941 and when Hitler incautiously declared war on the United States four days after the Japanese attack on Pearl Harbor, the de facto American-Soviet alliance became a reality.
Most of the early aid arrived on the dangerous “Murmansk run.” In raging seas and Arctic temperatures, convoys carrying American war materials and basic goods ran a gauntlet of German air and U-boat attacks, from Great Britain to the Soviet Arctic ports of Arkhangelsk and Murmansk. One convoy lost 70 out of 80 ships. Later in the war, the Pacific route, a short voyage across the Bering Straits from Alaska to the Siberian port of Vladivostok, made up nearly half the shipments, and one-third came over the mountains into Soviet Central Asia via the Persian Gulf.
