One thing in particular that he pointed out was just how the Nazis laid out exactly what their goals were (such as in Mein Kampf) but in the rush to appease, no one took it at face value. (Interesting to see Buchanan morph into Neville Chamberlain in this respect).
He also pointed out that the whole concept of "Kampf" is similar to "Jihad".
Thanks for the bump.
