Yes, it would have.
The Communists had more than enough faults, but they would, had they come to power (which wouldn’t have been too likely, since they had never been able to garner more than 16.9 per cent of the national vote, and often significantly less), they would have been against the war, and against genocide.
Had the hellhound been killed and his reign of terror collapsed, the Conservatives, the Liberals, the Catholic Centre Party, and last but not least, the Social Democrats, would have had to work out a compromise how to shape the nation‘s political future. They together would have been the majority against the extremists.
But to everyone in the resistance, no matter where, it was clear that peace was the first goal, for better or worse for Germany. There was nobody among them who thought that the war was winnable- no backstab legend this time 😉
Only a handful, rather naively, hoped for the best outcome of a future peace conference - it was more of a „God have mercy on us“ moment - but we shall, sadly, never know…but everything would have been better than what really happened 🙁
And about the atom bomb: America deployed so many resources to its development that the German efforts looked puny besides. Furthermore, there was no way in the Forties that a German bomb could have struck America, atomic or not. Germany had neither intercontinental ballistic rockets nor bombers suitable for such a task.
I don’t know about your opinion there.
Anyway, WHEN kill Hitler? What exactly is the alternative history?
Some have talked about as a baby. Some, what if WWI killed him?
I wonder if he got more attention with his artwork if he wouldn’t be quite what he became. Or, FTM, if the Allies hadn’t been overly punitive with WWI aftermath.
All innocent naive speculation, on my part, since I don’t know much.
Germans did have a bomber that could reach America in WW II—but it could not return to Europe. BUT with a nuke a one way trip would have been possible. Crew could ditch over Atlantic to be recovered by a U-Boat. They even talked about such things to hit New York—But it was practice with conventional bombs—but with a nuke—even a dirty bomb it might have been worth it. Japan even thought of hitting the USA with a plague bomb they perfected in China. One way attack on San Francisco or San Diego. They would have gladly given up a plane and crew to hit a US city.
