The only chance he had, while still taking Poland, was to not meaningfully attack France, Netherlands, or Britain. Make it clear he was willing to settle with them. None of those countries were thrilled to be in a war, that would have been the end of it with a new map of Europe.
The West didn't care about the Holocaust and felt more threatened by Russia. The war in the Pacific would have still happened of course. And there's a fair chance the West would have teamed up with Hitler to fight Russia.
So, unrelated, but does anyone know what movie that frame is from? Because I swear I remember starting it but I didn't get to finish it and I don't remember what it was but I kinda liked it. It was about something from space hitting earth I think?
And Hitler ended up in a ditch, covered in petrol, on fire, so, that's fun! I think that's funny, ‘cause he was a mass-murdering fuckhead. And that was his honeymoon as well!
Time was a real factor, Germany was on the verge of nuclear technology too. Many lives were spared because Hitler over extended himself. By the time the Allies were at Berlin they were on a campaign of submission.
Nikita Khrushchev, in his own memoir, stating clearly that the USSR could not have won the war on its own:
I would like to express my candid opinion about Stalin's views on whether the Red Army and the Soviet Union could have coped with Nazi Germany and survived the war without aid from the United States and Britain. First, I would like to tell about some remarks Stalin made and repeated several times when we were "discussing freely" among ourselves. He stated bluntly that if the United States had not helped us, we would not have won the war. If we had had to fight Nazi Germany one on one, we could not have stood up against Germany's pressure, and we would have lost the war. No one ever discussed this subject officially, and I don't think Stalin left any written evidence of his opinion, but I will state here that several times in conversations with me he noted that these were the actual circumstances. He never made a special point of holding a conversation on the subject, but when we were engaged in some kind of relaxed conversation, going over international questions of the past and present, and when we would return to the subject of the path we had traveled during the war, that is what he said. When I listened to his remarks, I was fully in agreement with him, and today I am even more so.

You're not wrong but a lot of those eastern front deaths came from the final days of the war as the allies marched on Germany's own land and as well as many battles fought by the Allies across both fronts. The US was instrumental to the pacific front. You'd also have a hard time convincing me France could have been liberated without the US's D Day Operations.
Most of the "what if" scenarios that I've come across focus on what if the Nazis hadn't attacked the USSR when they did. If Germany was fighting on one front at a time, the question becomes does Germany take the UK, and if so, does the US directly enter the war at all?
