Now, we are very good at saying that Japan would NOT invade Russia in 1941.
We have all the stat's to prove that it would be a bad move and that Japan had to go South insofar as the Northern Resource Area would take decades to develop and Japan was seriously running out of time.
Well and good.
However, Stalin kept massive forces in Siberia and clearly feared a Japanese attack, to the point of not even taking Sorge serious.
What did he know that we don't? Stalin was surely not stupid and must have looked at the same facts as us.
So?
