Sure, but in the end Stalin says "Yes" and that's it. Really. And Roosevelt says "Ok, Peace" and the shooting stops. It really happens like that sometimes.
Books have been written about the "Stalin Personality Cult", his enormous personal power and his perfect control over all matters of state. And you dismiss this with a few cute remarks.
For your remarkable claims, you will have to provide MUCH more evidence. Try this: google Stalin and start reading.
also let me caution you that probably unlike you I have actual experience living in Soviet Union (not under Stalin, fortunately) and getting to know the "evidence" first hand.
