One of the major factors contributing to the Allied victory in World War II was the United States' industrial capacity. Even before the war, the United States was busy manufacturing a massive amount of weaponry which it gave through the "Lend-Lease" agreement to the British and other Allied combatants. Once the country joined the war itself, it brought along a seemingly endless supply of equipment, vehicles and tanks. In the face of dwindling German wartime production, victory was only a matter of overwhelming the enemy with weapons that just kept on coming.
