He was like a lot of the nazi scientists in the sense that he was milking Hitler for funding money for his own research.
There was a lot of foot dragging among the nazi scientists which meant a lot of the nazi “superweapons” came just a little too late.
Very true, the Nazi “super weapons” proved to be too little too late to have had a chance to change the outcome of the war. But when you consider all of the areas they pioneered in, it is truly amazing. Including missiles and rockets, jet fighters, synthetic fuel, atomic weapons, super tanks, submarine warfare, massive rail guns, precision guided munitions...it is no wonder there was fierce competition for their scientists among the West and the Soviets as the war drew to a close.
