In fact I am proud of what the Germans were able to achieve in WW2. The pure military aspect, of course.
Here in Germany we had some kind of "ultra political correctness", you weren't allowed to say anything what Jesus wouldn't say aswell. Our German army, the Bundeswehr, is more kind of a militant pathfinder organisation. A Seargent got dishonorably (?) released because he told his recruits during MG shooting to shout "Mother****ers!". Basically you are there to carry a weapon, but don't think you are expected to kill someone. The Wehrmacht killed some people, and as the new, good Germans are the total opposite of the old, bad Germans, everything which looks like a tiny bit of aggression (or patriotism) is immediately related to WW2 and declared evil. It's a wonder that Germans still eat bread, as there were rumors Hitler did eat bread, too.
The younger generations here in Germany are tired of feeling sorry for something they didn't do themselves. So Hitler jokes are becoming very popular here, as it makes the whole thing less serious.
One of the most popular ones is to say first: "That's not funny. My grandfather died in a concentration camp." Everyone will feel embarassed, then you add: "He fell off a watchtower while he was drunk..."
Also a nice one:
Medvedev, Obama and Merkel are standing at a dock. Suddenly a submarine comes up. Medvedev: "Sis is Russian submarrine. Can stay underr waterr forr two mons!". Suddenly another submarines comes up, bigger than the first one: "Well, this is an American submarine, it can stay under water for half a year!". Merkel already starts to feel uncomfortable, because she doesn't know what to say now, as suddenly a third submarine comes up, much bigger than the two other ones, pushing them aside and almost making them sink. The hatch opens, and a man with beard and black cap comes out: "Heil Hitler! We need some diesel!"
A shorter one: Why are there so many avenues with trees in France? - Because the Germans enjoy marching in the shade!
