USA HISTORY

Detailed explanation-1: -This approach to foreign policy was called isolationism. To prevent an arms race that could lead to another world war, America signed a number of disarmament treaties to limit the size of naval fleets among Britain, France, Italy, Japan, and the United States.

Detailed explanation-2: -Isolationists believed that World War II was ultimately a dispute between foreign nations and that the United States had no good reason to get involved. The best policy, they claimed, was for the United States to build up its own defenses and avoid antagonizing either side.

Detailed explanation-3: -President Franklin D. Roosevelt understood, though, that the best way to keep American troops out of World War II was to help the British and French defeat Hitler without us. That required money, munitions and equipment-foreign aid that was explicitly banned by the Neutrality Acts.

Detailed explanation-4: -The United States remained neutral during the first two years of World War II. As the Axis forces conquered countries throughout Europe and Asia, Americans debated whether to aid the Allied powers economically and militarily.

Detailed explanation-5: -On December 7, 1941, following the Japanese bombing of Pearl Harbor, the United States declared war on Japan. Three days later, after Germany and Italy declared war on it, the United States became fully engaged in the Second World War.
