Think what way? What point do you think Pat was actually making? Please back this up with an exact quote from his article.
So, Pat thinks that if only the Poles had given up Danzig, Herr Hitler would have tended his garden quietly, painted some water colors, and stood as a bulwark against Bolshevism?
Obviously, Hitler would not have done that. He wanted lebensraum in the East at the expense of the Slavs and he was going to try to get it no matter how much appeasement the West attempted. His seizure of the rump of Czecheslovakia was proof of that. The same was true of Japan in China.
Anyone can see that. Anyone except modern day appeasers and crypto-Nazis.
