This is an interesting post from Jesse's Cafe Americain
"The capacity for self-delusion and a bad compromise is amazing, especially during periods of confusion, fear, and distraction. And the moral base in Germany at that interwar period was already notoriously relativistic and given to occultism, odd theories, and Nietzchean extremes. And after war, hyperinflation, and a new Depression, their spirit and will to resist evil was simply exhausted, especially when it was backed by systematic terror and force.
We ought not to be too critical of those people, many of the Americans included, who did not see the worst coming. Did you see the recent financial collapse coming, and what has followed? Do you even understand it yet? History may be amazed at your ignorance. And yet all the signs of trouble were there during the period from 1999 to 2007.
Some people were warning of the credit bubble, the imbalanced financial sector, and widespread fraud. And the American people were distracted by a 'war on terror,' and not the collapse of their lives and savings after the decimation from a brutal world war that left the flower of their youth dead, crippled, or broken."
