Allies

Explanation:

In September of 1939 the war broke out in Europe. Roosevelt announced that the United States would be neutral and indifferent. In September 1940, when England was threatened by the German invasion, the United States gave the British 50 old destroyers in exchange for naval bases in the western Atlantic. Two weeks later, Congress approved the first military conscription in times of peace in the history of the United States. By early 1941 England no longer had money to buy American goods, so Roosevelt convinced Congress to enact a "lease-lease" law. Through this program, the United States ended up "lending" US $ 13,500 million in war supplies to Great Britain, and another US $ 9,000 million to the Soviet Union.

By November 1941, US military planners were preparing for a Japanese assault, but they expected an attack to the south, to the oil-rich East Indies of Holland (Indonesia). Instead, Japanese bombers stationed on an aircraft carrier attacked the Pearl Harbor naval base in Hawaii. The surprise attack sank or damaged eight warships and destroyed almost 200 aircraft. The United States immediately declared war on Japan. Four days later, Germany and Italy, allies of Japan, declared war on the United States.
