Explanation:

The second World War started in 1939 it ended in 1945, and the United States didn't want any part of what was seen as another European War. So President FDR sold weapons, machines, and supplies to Britain until he could sway American's opinions, but in the end he wouldn't have to; for on December 7th, 1941 U. S. Navel Forces were attacked by the Empire of Japan. This unprovoked attack caused the entire country to go to war.
