On July 18, 1941, FDR did not initially want to but continued to cut off Japan’s oil exports that we had been supplying for them. Later on November 26, 1941, Japan had decided that they were going to fight back about the canceled oil exports and sent off their troops by attacking Pearl Harbor when the U.S. least expected it. December 7, 1941, is known as the day that will live in infamy because of the surprised attack from Japan. On this day, Japan had already been on their way for a bit and began to drop numerous bombs and shooting many from their army and began their attack plan. Earlier that day yet not too long before the attack began, Joseph Rochefort had noticed some very strange readings from the radar which read that many aircrafts were headed our way. After the bombing which left many civilians, 2,335 military personnel dead, and also eight damaged U.S. Navy battleships with four sunk, FDR had decided to declare war in Japan for their unforgivable actions.
