Strike North. Japan vs. the Soviet Union, 1941 Strike North presumes that Imperial Japan has decided to invade the Soviet Union in 1941, instead of going to war with the United States. Conceptually, a Japanese invasion of the Soviet Union would be in conjunction with the German attack on the USSR (Operation Barbarossa) on 22 June, 1941. The strategic possibilities of this alternative course are incredible; The Soviets will be under the pressure of fighting a two-front war. However, by following this strategy, the Japanese would be temporarily abandoning their planned invasions of the resource regions of the East Indies and beyond, leaving Japan less than a half-year of oil to sustain their war effort.
