I don't think you fully appreciate the degree of control that Stalin had over the USSR in the time period.

He was a dictator. But he was also a leader of a political entity.

This man once received a 45 minute standing ovation because nobody wanted to be the first man to sit down and risk execution.

What's your point? This is standard for most dictators.

The degree of control that he had over the military was also stunning. Numerous encirclements occurred because the Soviet general refused to evacuate without approval from Stalin.

Yes, it's called being a dictator.

Listen I didn't say he wasn't a dictator. But once a dictator dies, the world doesn't end. Life goes on. The political/military structure is in place. Okay?

If he died, the infighting and intrigue might have been enough to give the Germans a huge advantage (albeit a temporary one).

Even with infighting, the germans would have lost. That's how much of an underdog germany really was. The germans were outnumber 16 million to 4 million. And outgunned in every category ( tanks, planes, etc ). And most importantly, the soviets had tons of resources and the germans were running out of resources.
