Hitler pissed off because the awesome Germans left the fatherland for America.
Kind of like when after we beat the Russians to the moon, Von Braun was asked how we beat them to the moon when they were ahead of us to start with, Von Braun said, “Our Germans were better than their Germans.”
“Von Braun said, “Our Germans were better than their Germans.”
LOL, I have never heard of that and I’m a fan of Von Braun.
