What if Stalin got it together during Operation Barbarossa more quickly?

[Vera Strawberry]

Stalin's initial response to Operation Barbarossa was far from good. At first, he refused to believe an attack was happening. When it became clear that it was, he assumed it was being carried out by rogue Wehrmacht elements against Hitler's orders. Once he could no longer deny that Hitler had backstabbed him, he had a nervous breakdown and holed himself up in his dacha for several days, refusing to see any visitors or take any calls. It was partly thanks to all of this that the Germans were able to get as far as they did.

What if Stalin had acknowledged Hitler's betrayal more quickly and not broken down? Could it have shortened the war?

The question that comes to mind is how does this end up worse for the allies.

Russians end war in the West on the French Border?

Germans give up earlier on Eastern Front and cut a separate peace deal with Stalin?

Perhaps He micromanages at the beginning too much leading to even bigger defeats for the his forces.
