Seventy years ago, on December 7, 1941, Japan launched a surprise attack on the United States. In just two hours it crippled a large part of the U.S. fleet docked in Pearl Harbor and, in one swift stroke, forever destroyed U.S. isolationism, unified the country for war, and made the conflicts raging in Europe, Asia, and Africa one truly global war.
The U.S. may have been expecting war but the attack on Pearl Harbor took it by surprise. Yet eleven months before, one voice predicted such a possibility. On January 27, 1941, the U.S. ambassador in Japan, Joseph Grew, cabled the White House warning that the Japanese might “attempt a surprise attack on Pearl Harbor using all their military facilities.”
As 1941 wore on, the likelihood of war became more apparent but the U.S. ignored Grew’s prediction, believing that conflict, if it came, would either start in the U.S.-controlled Philippines or the Dutch or British possessions in Southeast Asia.
