March: Lend–Lease approved the US Congress.
The program would eventually supply the United Kingdom and other US allies against Hitler (Russia, France and China) with vast amounts of war materiel between 1941–1945. Approximately $50 billion–worth total, of which about 60 percent would go to the UK.
Lend–Lease was Roosevelt’s not–so–delicate dance to circumvent strong isolationist sentiment in the USA, and Roosevelt’s own campaign promises.
