the Germans' use of unrestricted submarine warfare
When World War One developed, the US followed a policy of neutrality towards the nations involved in that conflict. In 1917, however, the German announcement that it would resume unrestricted submarine warfare pushed the US into the war against Germany and her allies.
In WW1, the German policy of unrestricted submarine warfare irritated neutral nations such as the United States and eventually helped public opinion to support the US entry into the war. In WW2 the German policy of unrestricted submarine warfare in the Atlantic irritated nominally neutral nations such as the United States and provided a rationale for increasing US support of Britain and its allies. In WW2 the American policy of unrestricted submarine warfare in the Pacific probably contributed to the degradation of Japanese economic capabilities as the war progressed.
