von Braun just wanted to build rockets. He was a Nazi, yes, and he did Nazi things, but he would have been (and was) just as loyal to any other country that let him build rockets.

Musk, OTOH... joke's on us, he's into that shit.

My understanding is that von Braun was fine with using slave labor to build the wartime rockets. He wasn't just some nerd totally detached from Nazi atrocities.

I don't know what Musk's real politics are, but at the moment at least there is no evidence that he is as bad as von Braun.
