The axis have been strenghtened in Revised to balance the game. Although its far from historical (russia produced 4 times as many tanks as the germans in 42) its necessary if the game should be playable

If Germany didnt declare war against russia in summer-41, the war would have ended after moths months. Japan would not bomb pearl, germany and Britain would eventually sign a truce, or brittain would have been forces to surrender.

But Germany wanted war against russia nomather what, Hitler hated communism as much as the jews.
So , if we say Russia didnt exist, USa wouldnt get involved in the war, and britain would loose against ger and italy.
End of story

United Kingdom 8) , for some reason, its always uk who does the D-day

Only buy bombers and atrat-bomb germany. Germany will not keep up against the russians when their total income is low

I think that a war that involved only Russia and Germany would be just the same as the war was originally. The Germans pushed almost every tank, man and artillery into russia in the first place. Only in 1944 the allies came to a sort of “rescue” and then Russia had full controll. The answer is clear :D
