American industry focused on the war effort. Women built many of the 300,000 aircraft, 5,000 cargo ships, and 86,000 tanks while the men became soldiers. The United States fought with Britain and the Soviet Union against the German Nazi threat in Europe. From the time that Germany and the Soviet Union invaded Poland in 1939 (Germany invaded the Soviet Union in 1941) until the German surrender in 1945, millions of people died. Millions more were killed in the Holocaust, the Nazi regime’s mass murder of Jews and other groups. Fighting continued in Asia and the Pacific Ocean even after the war ended in Europe. These battles were among the bloodiest for American forces.
美國工業(yè)將注意力集中在了戰(zhàn)爭上。男人們在前線重逢陷陣，女人們則在后方制作了多達30萬架的飛機、5000多艘的貨船和86000輛的坦克。美國聯(lián)合英國和蘇聯(lián)共同對抗歐洲的納粹德國。從1939年德國和蘇聯(lián)侵占波蘭（德國在1941年侵占蘇聯(lián)）到1945年德國投降，數(shù)百萬人死于非命。更有數(shù)百萬人死于納粹黨組織的大屠殺，這些屠殺主要針對猶太人，當然還有一些非猶太人有遭到屠殺。在歐洲戰(zhàn)場結(jié)束戰(zhàn)事以后，亞洲和太平洋地區(qū)仍然堅持作戰(zhàn)。這些戰(zhàn)爭也成為美國歷史上最血腥的戰(zhàn)事。
