I read a comment on Reddit awhile back saying that Claus Von Stauffenburg was not necessarily against the Holocaust but believed that Germany needed to end the war for its own sake, which led me to ask this question. Any insight?
First, Stauffenberg and the other Conspirators aren't the resistance leaders. The resistance in Germany was very split up, and there were various other, completely different groups that never had anything in common with Stauffenberg.
I think there is no comprehend thought about the conspirators and the Holocaust. Some of them definitely were in the know about them. What we can say is, that they weren't antifascists in the common sense. They were Prussian aristocracy, nationalist and militarist through and through.
What they wanted is to end the war, not out of some noble consciousness, but because they saw that they lost. Ending the war is, as far as I know, they only really stated goal that all together shared. Apart from this, there would've been a lot more conflict on what Germany without Hitler should look.
