What would the USSR have looked like if Stalin in never existed? Assuming everything goes the same way during the Revolution, what would have happened after Lenin died? I don't think Trotsky could have realistically succeeded Lenin, since he was hated in the Party. Would somebody like Kamenev, Zinoviev, or Bukharin have come to power? How would WWII have turned out? What about afterwards? How would the rest of the early 20th century look for the USSR?
