Lefties Spinning and Spinning - part 2

In parts 2 and 3 I cover the first part of David Talbot's book The Devil's Chessboard on Allen Dulles, in which he exaggeratingly obsesses on the Holocaust as a way to condemn Dulles as a Nazi-sympathizing devil right out of the box. Is this history? Well, what is history exactly? Who writes it? Can anyone question it?
