Imagine a post-WWII Germany where the Nuremberg Trials never happened.
Picture this:
Germany, after WWII. A fresh start for the country. Except there have never been the Nuremberg Trials and all the old Nazis are still hanging around, doing Nazi-politics, giving lectures and speeches in favor of national-socialism, writing books how great everything was in Nazi-Germany, drumming up voter-support for the latest slate of Neo-Nazi-politicians...
This is exactly what the US has become. A country where committing war-crimes has no consequences.
"Sure, we tortured and killed people in the concentration-camps, but we deemed it necessary at the time. Millions of Jews were systematically exterminated, but all the available intelligence back then hinted at a massive jewish conspiracy to take over the world and wage biological warfare against Germany in particular. At that time, we deemed our actions totally justified to defend Germany against this conspiracy.
I think it is great for Germany to have this discussion. This discussion proves that we are facing our past and that we have the guts to face it with hard, uncompromising conversations. You should read the latest books by Reichsmarschall a.D. Hermann Göring or Reichskanzler Albert Speer."
