a post about how many nazis remained in positions of power is made, the op is called a tankie and people defend the decision to keep nazis around
He was a Nazi party member, had an SS ranking, and saw the conditions of the slave labour used in the rocket program. But also it's questionable how much of that was because he wanted to keep doing rocket science, and how much was because he was a Nazi.
It sounds like he was a Nazi, you don't get to join the SS, oversee slave labour camps and executions, and not be a Nazi. I don't think his motives mattered if he was willing to kill 20,000 people in his slave rocket factory. He should have been hanged, his expertise be damned.
