Berlin has innumerable official monuments and reminders to communicate the horror of the holocaust, including a very haunting memorial just opened one block from the Brandenburg Gate. The Germans are absolutely committed never to forget what can happen when a civilized society surrenders itself to racial hatred, and they are absolutely not sweeping their history under a rug.
Of course they're not, they're just bulldozing Checkpoint Charlie because they'll remember their post-war sins better that way.
They've got a LOT to remember. I guess killing their own for wanting freedom doesn't fit so well these days, when they'd probably like a more...uh, "progressive" society.
Except for this history...
They seem to want to sweep the Cold War under the rug... oh, but that's when West Germany was allied with the evil Americans, so it is essential to erase or rewrite history.
