Previous - Japan attacks America (CYOAH)
Roosevelt knew a war on two fronts would be disastrous. He decides to try negotiating with the Japanese. However, the Empire of Japan demands Hawaii and all American Pacific territories. The United States reject that, but a compromise is worked out within a few weeks. Japan would get control over Guam and the Philippines in exchange for a non-aggression pact between the two nations.
With the Japanese taken care of, the massive American army moves into the Soviet Union. Tanks, ships, and aircraft are being produced en masse for the imminent war. All that needs to be done now is find a place to enter through.
