I was in East Berlin for a few hours or so in 1980. They were still doing reconstruction of bombed sites then, 35 years after the end of WWII. BTW, today is the 67th Anniversary of V-E Day.
Europeans have had a lot of war over the centuries and are well versed in how you deal with it. For the GDR it was just a case of waiting until the foreign occupiers left.
I tried celebrating by pulling one of these moves and promptly got the cops called on me. < |:(~
