The difference between countries like Cambodia, Uganda, Russia and the like were they were third world countries and the people were little more than peasants.
Germany was a word leader, that was very civilised and produced great scientists, architects, composers and the like. But it wasn't a coup that got Hitler into power, millions of Germans voted him in.
Of course nowadays you hear German's say they didn't agree with him, but they didn't say that when they were stomping all over Europe. He was the best thing since sliced bread. Thousands of them glassy eyed turned up at massed rallies screaming sieg heil.
You have to be a very sick individual to send women and children into a gas chamber or to do the vile experiments they did on young children in the name of science. Yet they never had a shortage of recruits.
The Waffen SS i admit were very brave and loyal soldiers, but they also took turns in the death camps.
It wasn't just the SS who carried out atrocities either, the Wermacht also did the same in occupied countries. Field Marshalls like Jodl and Keitel were hung for war crimes against humanity. Rommel only turned against Hitler when he thought Germany was losing the war. Before that he was a dedicated Nazi.
Then less than thirty years later we were all in the European Union as though it had never happened.
Sorry doesn't really cover things like this.
Germany should have been an outcast for at least one hundred years.
