i don't think that this may happen. otherwise,there would be thousands of neo-nazis lurking around in front of all sorts of german WW2-arms in the museums.
There is a vast difference between a Mauser and a Pocket Battle ship. Most german WWII arms would have been made with or with out the Nazi's. Indeed, many of them were around before the nazi's came to power. A Pocket battleship however, such as the Graf Spee was a Nazi icon of defiance against the treaty forced upon them after WWI. It was their way of saying "We can still build powerful warships even with your restrictions!" So basically there is a difference. And I still want the Graf Spee to stay put. She was scuttled, end of story.
