The U.S. Presidents in World War II played pivotal roles during one of history's most significant conflicts. With the nation divided over involvement in the war, the leadership styles and foreign policies of these presidents shaped the course of U.S. history. Franklin D. Roosevelt (FDR) was the key figure for the United States at the war's onset, while Harry S. Truman took over towards the end and made critical decisions regarding the war's conclusion.
