Very true, WT. Add to that the daily injections and supplements he was receiving from his quack physician, Dr. Theo Morell, and you have a Hitler who was really losing touch with all reality on a daily basis.
Another point to add is that Hitler, like our recently departed friend Saddam, controlled every aspect of life for Germany. At a certain point; whether ordinary Germans or not,fear of the Gestapo and their brutalities made people look the other way at the excesses of the Nazi regime.
