Practically, the Nazis could not have liquidated all of the Slavs. I am not aware that they planned to. They planned “Germanize” many Slavic lands, to deport their populations to Siberia and to use Slavs as slave labor. I do not deny that millions of Slavs died in the Holocaust. However, at the end of the war; Eastern Europe remained largely Slavic but was almost devoid of Jews. Slavs were not exterminated. Jews were, and as it happens they were often killed by Poles, Ukrainians, etc., rather than by Germans.
There are many parallels between what the National Socialists and the Soviet Socialists did. The USSR “Russified” its subject nationalities (esp. the Baltic states), deporting much of their populations to remote areas and replacing them with Russians. They operated slave labor camps long before the Nazis did, and filled them with millions of Balts, Ukrainians, and other groups. Just like the Nazis, the Soviets killed more in their camps during the war than before it. For Buchanan to pretend that the National Socialists didn’t plan their evil deeds until the nasty imperialist Brits provoked them is just as ridiculous as saying that the West provoked Stalin. Conquest, mass murder, torture, and enslavement are what socialism is all about. If the people around Hussein Obama are given free rein, we will have them in America also.
