Answer:
United States.
Explanation:
The United States was reluctant to join the war effort- congress specifically. Britain was left alone to fight Germany for most of the war. France was occupied by Nazis- so the most they could do was fight sporadic guerilla battles. The US finally joined the war after the bombing of Pearl Harbor.
