Must say I cannot think, like T.A. says, that there would be anything interesting or valuable for the Japanese to get in Siberia (?). Maybe some mines for resources but very little of that, I guess.
However the Japanese did have the northern and southern approach to the war possibility, and they decided to take the latter. I donīt know what were the goals for the northern approach.
The German attack was cancelled early in Decemeber and the Russian counter-attack, if I remember correctly, started after that. The first time the troops from east were used in late Ocotber, but it seems that the troops were not needed to stop the Germans, the weather did it as well as getting no supplies of men and food, but the troops were needed for the counter attack that might have destroyed the whole of Army Group Center.
