In what year did the U.S. enter the war?

It took a while for the U.S. to get their head in the game. It wasn't until Japan attacked Pearl Harbor on December 7, 1941, that Roosevelt changed America's neutral status to "all systems go!" Four days after the attack, Hitler declared war on the U.S., and the rest is history.
