U.S. in WW2
Causes for the united states entry into World War two.
Rise of Totalitarian Regimes
The end of WW1 was fallowed by the demolish of many current governments by the replacement of their leaders, it is that which lead to the rise of totalitarian regimes such as Germany lead by Hitler Italy lead by Mussolini and Hideki Tojo in japan.
UBoat Crisis
Another factor that lead the U.S. to join the war was the UBoat (seen in Fig. 3) blockades sinking allied ships in the northern Atlantic and creating economic blockades, leading to the battle of the Atlantic.

Cash And Carry Policy
Another cause was the great depression. With so many people out of a job and money a war seems like a great idea for profit, selling to either or both sides leading up to the creation of the Lend-Lease Act of 1941
Pearl Harbor
The attack on Pearl Harbor was a surprise attack by the Japanese Navy against the United States base at Pearl Harbor, Hawaii, on the morning of December 7, 1941. The attack led to the United States' entry into World War II.
