I assume you're talking about the Revolutionary era. The colonists wanted to go to war for their independence. They didn't have representation in the government, yet they were still taxed.
The Japanese bombed Pearl Harbor before America joined the war. America did not plan on joining the war, but was going to support their allies with resources. Japan had wanted exports from America, but the U.S. refused. Since the American government would not give to Japan, Japan decided to attack Pearl Harbor. This made the Americans furious as they had not yet enlisted and saw this as an act of terrorism. They immediately took action and joined the war.<span />
