On December 6, the Japanese government began sending a long message to its diplomats in Washington. The last part of that message arrived in the early-morning hours of December 7. Japanese diplomats Nomura and Kurusu prepared for a final meeting with Secretary of State Hull, knowing that they were being ordered to break off all negotiations with the U.S. What they didn't realize was that the same message had been decoded and rushed to President Roosevelt and to the high commanders of the U.S. Army and Navy. The U.S. was now aware that Japan might strike somewhere in the Pacific, but a warning did not reach Pearl Harbor until nearly 8:00 a.m., Hawaii time. By then, Nomura and Kurusu were in Secretary Hull's office, and Japanese bombs were falling onto the neat lines of U.S. warships in Pearl Harbor's "Battleship Row."
