Why Did Japan Attack U.S?
Of all the days that will "live in infamy" in American history, two stand out: Sept. 11, 2001, and Dec. 7, 1941.
But why did Japan, with a 10th of our industrial power, launch a sneak attack on the U.S. fleet at Pearl Harbor, an act of state terror that must ignite a war to the death it could not win? Were they insane? No, the Japanese were desperate.
To understand why Japan lashed out, we must go back to World War I. Japan had been our ally. But when she tried to collect her share of the booty at Versailles, she ran into an obdurate Woodrow Wilson.
Wilson rejected Japan's claim to German concessions in Shantung, home of Confucius, which Japan had captured at a price in blood. Tokyo threatened a walkout if denied what she had been promised by the British. "They are not bluffing," warned Wilson, as he capitulated. "We gave them what they should not have."
In 1921, at the Washington Naval Conference, the United States pressured the British to end their 20-year alliance with Japan. By appeasing the Americans, the British enraged and alienated a proud nation that had been a loyal friend.
Japan was now isolated, with Stalin's brooding empire to the north, a rising China to the east and, to the south, Western imperial powers that detested and distrusted her.
When civil war broke out in China, Japan in 1931 occupied Manchuria as a buffer state. This was the way the Europeans had collected their empires. Yet, the West was "shocked, shocked" that Japan would embark upon a course of "aggression." Said one Japanese diplomat, "Just when we learn how to play poker, they change the game to bridge."
Japan now decided to create in China what the British had in India – a vast colony to exploit that would place her among the world powers. In 1937, after a clash at Marco Polo Bridge near Peking, Japan invaded and, after four years of fighting, including the horrific Rape of Nanking, Japan controlled the coastal cities, but not the interior.
When France capitulated in June 1940, Japan moved into northern French Indochina. And though the United States had no interest there, we imposed an embargo on steel and scrap metal. After Hitler invaded Russia in June 1941, Japan moved into southern Indochina. FDR ordered all Japanese assets frozen.
But FDR did not want to cut off oil. As he told his Cabinet on July 18, an embargo meant war, for that would force oil-starved Japan to seize the oil fields of the Dutch East Indies. But a State Department lawyer named Dean Acheson drew up the sanctions in such a way as to block any Japanese purchases of U.S. oil. By the time FDR found out, in September, he could not back down.
