The only people ever held “Accountable” in the GDR were Honecker, and a few other top GDR leaders.
They were not held accountable for Crimes like the mass murders in the NKVD “special Camps, or the later crimes of the Stasi, but for the killings of those attempting to escape from the GDR to the west, across the Berlin Wall.
And even then, Honecker managed to avoid penalty in the end for “health Reasons”.
Even worse, communists were incorporated by way of the green movement into the governing of the unified Germany and European Union. I am exposed to neighbors who see Uncle Sam as the Great Satan but are apparently incapable of recognizing any evil on the left.
The conspiratorial paranoia here in Germany against international financiers (read Jews) is growing daily yet the bigotry is so primitive and ill-informed that they have never even heard of George Soros. But God help the fool who publicly denies the Holocaust in Austria.
