The Japanese military had long dominated Japanese foreign affairs; although official negotiations between the U.S. secretary of state and his Japanese counterpart to ease tensions were ongoing, Hideki Tojo, the minister of war who would soon be prime minister, had no intention of withdrawing from captured territories. He also construed the American “threat” of war as an ultimatum and prepared to deliver the first blow in a Japanese-American confrontation: the bombing of Pearl Harbor.

And so Tokyo delivered the order to all pertinent Fleet commanders, that not only the United States—and its protectorate the Philippines—but British and Dutch colonies in the Pacific were to be attacked. War was going to be declared on the West.
