I didn’t even know Disney had hired Wernher von Braun, though i knew NASA did (I found an article about both). Tom Lehrer even wrote a song about it. You should listen to it, it’s funny.
No, I don’t think hiring von Braun was apolitical, either for Disney or for the U.S. government. But Disney was an antisemitic fascist-sympathizing fuck to begin with, so it’s not exactly surprising.
