Yamamoto listens to the worries of local commanders and does not board his transport aircraft, instead finishing his tour on-board a navy vessel. This causes the American attack to be a failure, and the Allies believe that the Japanese may be aware of the hacking of their codes. This results in a series of events that culminate in Japan surrendering without the use of the A-Bomb, Yamamoto becoming leader of Japan, and the USSR never gaining a foothold in Southeast Asia.
