how did the united states go from neutrality in the 1930s to war in 1941
Neutrality Acts of 1930s After repeated attacks by German submarines on U.S. ships, Roosevelt announced on September 11, 1941, that he had ordered the U.S. Navy to attack German and Italian war vessels in the "waters which we deem necessary for our defense". Following the sinking of the U.S. destroyer Reuben James on October 31, many of the provisions of the Neutrality Acts were repealed on November 17, 1941: merchant vessels were allowed to be armed and to carry any cargoes to belligerent nations. The U.S. formally declared war on Japan on 8 December 1941 following the attack on Pearl Harbor of the previous day; Germany and Italy declared war on the U.S. on 11 December 1941, and the U.S. responded with a declaration of war on the same day.
Military history of the United States during World War II The war against Germany involved aid to Britain, her allies, and the Soviet Union, with the U.S. supplying munitions until it could ready an invasion force. U.S. forces were first tested to a limited degree in the North African Campaign and then employed more significantly with British Forces in Italy in 1943â€“45, where U.S. forces, representing about a third of the Allied forces deployed, bogged down after Italy surrendered and the Germans took over. Finally the main invasion of France took place in June 1944, under General Dwight D. Eisenhower. Meanwhile, the U.S. Army Air Forces and the British Royal Air Force engaged in the area bombardment of German cities and systematically targeted German transportation links and synthetic oil plants, as it knocked out what was left of the Luftwaffe post Battle of Britain in 1944. With the Soviets unstoppable in the east, and the Allies unstoppable in the west, Germany was squeezed to death. Berlin fell to the Soviets in May 1945, and with Adolf Hitler dead, the Germans surrendered.
