Answer:
not want to
Step-by-step explanation:
The First World War caused many casualties, and many Americans remembered the horrors of that war. As a result, the Americans wanted to continue Wilson's isolationist policy and not join into the war because it would cause casualties. The 1939 presidential election saw Wendell Willkie face off against recurring Franklin D. Roosevelt. Neither side wanted to join the war.
Roosevelt would win the election, and would keep America out of the war, until Pearl Harbor.
American isolationism was an idea traditional started by James Monroe and the Monroe Doctrine, stating that the europeans couldn't intervene in america and the countries from North and South America (including the USA) would stay out of europe.
