Why was America hesitant to join the war?

The United States was very reluctant to enter World War I for several reasons. One reason had to do with trade. We were trading with countries on both sides of the conflict. Before the United States joined World War II in response to the Japanese attack on Pearl Harbor, the great battle had been raging in Europe since 1939. While the British and Russians struggled against the German Reich, the United States remained officially neutral and refused to enter the war.  Hope this helps!! :D
