unrestricted submarine warfare
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.
During World War I, Germany's goal in returning to unrestricted submarine warfare in 1917 was, quite simply, to bring the long war to a quick end. Realizing that this decision could bring war with the United States, German leaders calculated that their submarines would end the war before American involvement could make a difference.
France and Britain never went to war against each other. The United States entered the war because of Germany's unrestricted submarine warfare and the their telegraph to Mexico telling to attack.

On August 4, 1914, President Woodrow Wilson proclaimed U.S. neutrality in the European war.

When Germany announced on January 31, 1917 a policy of unrestricted submarine warfare, the United States cut diplomatic ties with Germany.
Woodrow Wilson asked Congress to declare war on Germany on April 2, 1917.
