Nobody should be surprised. The Nazi's ideas of eugenics were born in America. In 1939 the second-largest Nazi party was in America. A lot of Americans at the time thought we should be fighting for the other side.
There was a Nazi rally at Madison Square Gardens. The US is very nationalistic (How many countries force their children to pledge alliance to the flag daily?) and that can easily become a problem.
As a German defence company, we feel a special responsibility to contribute to the culture of remembrance and commemoration in the context of the Second World War. We have thoroughly examined and documented our role and our transgressions during the Nazi era.
Well, that's only fair. They get to be on in the Allies this time around. We (the US) are going to have to work with ... wait, Italy already dumped us. So, Japan? Can we bring back Imperial Japan for our side?
