Germany is and for a long time will be viewed through prism of 20th century history. Not so much Germany, more like Germans. Militaristic and serville nation eager to go to war when some leader say so, no matter if the leader is Kaiser or Fuhrer.
That's why. Does it represent todays Germany and its citizens? No. But your ancestors were center piece of two most brutal conflicts in the history of mankind and it will take a long time until people will forget. At least a few more decades, until people who actually lost their direct relatives in Germany's last conquest attempt die out.
I get it, it has to suck, but that's how it is.
