* Economic aid: The US provided economic aid to its allies through the Lend-Lease program. This program allowed the US to lend Allies military equipment, supplies, and food, all of which could be repaid after the war. The Lend-Lease program was essential in helping the Allies fight against the Axis powers.
* Military equipment: The US provided military equipment to the Allies through the "Cash-and carry" program. Under the Cash-and carry program, the Allies could purchase military weapons, ammunition, and planes that could be paid for in cash to carry from the US, provided they had the means to transport them.
* Military aid: The US also provided military aid to its Allies. This included sending troops to fight alongside Allied troops, providing air support, and providing naval support. The US also sent military advisors to help train Allied troops and develop military strategies.
