It is OK by him for Nazi atrocities, centuries of religious cleansing by the Muslims and others because the crusades and defense or the free world were mostly by Christians. Kinda shows the mindset of the talking heads.
To be fair there were times certain allies did go overboard (e.x. the rape of Berlin mostly by the Soviets, massacres of German civilians in Czechoslovakia).
You know the sad thing is, if people like him were in charge back then we would probably lost, and the funny thing because of his skin color if the axis powers would have won the war he would be exterminated because of who he is.
