Nowadays people think that every German soldier was a war criminal or camp guard. They know little or nothing about ww1, Versailles, the conditions of a merciless war or the criminal side of communism. For the average American ww2 is a series of awful Hollywood movies. So yeah, the power of pop culture indeed.
Btw men like Heusinger and Speidel received their NATO positions because of their (partly justified) treason during the war. Apart from that the Americans always have been prepared to make friends with anyone they could use for their own interests. After all the Uncle Joe nonsense during the war the positive view of the American people about Russia had to be changed, so the Germans became useful again. Not very styleful perhaps, but a very necessary adjustment at the time.
