when did the us start preparing for ww2
Military history of the United States during World War II American public opinion was hostile to Hitler's Germany, but how much aid to give the Allies was controversial. Public opinion was even more hostile to Japan, and there was little opposition to increased support for China. By 1940 the U.S., while still neutral, was becoming the "Arsenal of Democracy" for the Allies, supplying money and war materials. The sudden defeat of France in spring 1940 caused the nation to begin to greatly grow its armed forces, including the first peacetime draft. After the German invasion of the Soviet Union in June 1941, America began sending Lend Lease aid to the Soviet Union as well as Britain and China.[5]
United States in World War I The American entry into World War I came in April 1917, after more than two and a half years of efforts by President Woodrow Wilson to keep the United States out of the war. Apart from an Anglophile element urging early support for the British, American public opinion reflected that of the president: the sentiment for neutrality was particularly strong among Irish Americans, German Americans and Scandinavian Americans,[2] as well as among church leaders and among women in general. On the other hand, even before World War I had broken out, American opinion had been more negative toward Germany than towards any other country in Europe.[3] Over time, especially after reports of atrocities in Belgium in 1914 and following the sinking of the passenger liner RMS Lusitania in 1915, the American people increasingly came to see Germany as the aggressor in Europe.
