Pat Buchanan Doesn't Know History

According to this post Pat Buchanan has become a Holocaust Denier. He seems to believe that if WWII hadn't started Hitler wouldn't have attempted to destroy the Jews. Conveniently he also blames the War on Churchill. I guess all those laws and attempts to remove Jews from German society from 1933-1939 were also caused by the War? This is just crazy. If I ran MSNBC he wouldn't show up there again.
