Adolf Hitler's Declaration of War against the United States at Wikisource

On 11 December 1941, four days after the Japanese attack on Pearl Harbor and three days after the United States declaration of war against Imperial Japan, Nazi Germany declared war against the United States, in response to what was claimed to be a "series of provocations" by the United States government when the U.S. was still officially neutral during World War II. The decision to declare war was made by Adolf Hitler, following two days of consultation.^[1] It has been referred to as Hitler's "most puzzling" decision of World War II.^[2] Publicly, the formal declaration was made to American Chargé d'Affaires Leland B. Morris by German Foreign Minister Joachim von Ribbentrop in the latter's office. Benito Mussolini also announced Italy's declaration of war against the United States on 11 December.^[3] Later that day, the U.S. declared war on Germany, with Germany's action having eliminated any remaining meaningful domestic isolationist opposition to the U.S. joining the European war.
