Answer:
A. Two years
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.
In the days before Germany surrendered on May 8, 1945, President Harry S Truman appointed Associate Supreme Court Justice Robert H Jackson to be the chief prosecutor representing the United States in the proposed trials for the European Axis powers. Jackson helped lead the Allies—American, British, French, and Soviet governments—to an agreement called the London Charter, setting the procedures for the Nuremberg Trials. The London Agreement created the International Military Tribunal (IMT) on August 8, 1945, where each of the four Allied nations appointed a judge and a prosecution team.
