UNITED STATES OF AMERICA

During the First World War, the United States stood apart from the conflict. Faced with threatening Germany, the United States entered the war in 1917 and played a decisive role in the victory. The post-war period experienced an extraordinary economic boom which confirms the role of the world's leading commercial and financial power achieved before the First World War. In such euphoria, the economic crisis born in October 1929 led to a real economic paralysis which created seven million unemployed in two years. The election of Roosevelt in 1932 made it possible to overcome the crisis with the interventionist policy of the "New deal" but reduced the influence of the United States on world politics while Europe was sinking into totalitarian regimes. Re-elected in 1940, Roosevelt made the United States the arsenal of democracies, and the Japanese attack on Pearl Harbor in 1941 threw the American people into World War II..
