There will be no civil war in russia after their defeat. They were all conditioned into complete apathy (that's why all other dictators and wannabes are paying attention). That's why most of those who join today, do that simply for money.
So all that might happen is mafia clashes as they will establish new spheres of control and then it will come back to the rise of the next "great" leader.

Pretty much. The soviets have systematically cultivated political apathy and pootler has brought it to the next level. Imagine having access to millions of bodies and nobody cares when you expend a million or two. That's dictator's wet dream.
