When the U. S. entered WWII, President Roosevelt decided to concentrate the nation's war effort on defeating the Axis powers in Europe first. What was the main reason for this decision?
a. Japan was geographically isolated, making it difficult to mobilize troops and supplies to the area.
b. The United States had lost too many of its battleships at Pearl Harbor to be able to defeat Japan first.
c. If Great Britain and the Soviet Union fell to Germany, the United States would stand-alone against the
Axis powers in Europe.
d. The crimes of Hitler were so terrible that it was essential to defeat Nazi Germany first.
