Best Answer - Chosen by Asker:

The US was leaning toward war by 1940!. The Lend-Lease act was passed, allowing the US to supply Britain (and later other allies, including the Soviet Union) with equipment and food, and Germany's efforts to sink the ships carrying those supplies would probably have led the US to war anyway!. However, Germany's ally, Japan, feeling that the US was actively seeking to reign in their expansionist policies across Asia, attacked the US fleet at Pearl Harbor, December 7, 1941, causing the sudden and instant plunge into war!.Www@QuestionHome@Com
