Compare and contrast the American reactions to World War 1 and World War 2?

Both wars America didnt want anything to do with. at first. it cost to much money to go to war plus they had previously sworn they wouldn't get cought up in European affairs. so they were trying to stay out of both wars. one war they joined in on because German u boats were bombing their ships for no reason killing many innocent Americans. the other war they joined because the japenese bombed pearl harbor. but in the beginning, American reactions to the wars were neutral because thay didnt want to get involved.
