Yacov and Mord, you are correct 100%. Communism is "International Socialism", Nazism is "National Socialism" (which subsequently had been in practice a globalist ideology). The only difference between National Socialism and Communism was its embracing Madam Blavatsky's Theosophy. Theosophy is where the entire racial aspect professed by Alfred Rosenberg and the Thule Society's: Nazism. If you look at the practice of both Communism and Nazism you will see they are both VERY similar, to the point of almost being identical in practice. Nazi Germany "Nationalized" everything as well did Russia. Both were financed by American Wealth. Nazi's had concentration camps and massive slave labor and the Soviets had the Gulag system and more White slaves than the entire British Commonwealth during the hey days of slavery. 6 million Jews died in the Holocaust while a comparable number died in the Gulags only thanks to "Political Correctness" and whitewashing Communism one often forgets this fact. Nazis looked down on the Poles, Slavs, Ukranians, Gypsies and Jews while the Soviets did the exact same after The Great Purge in the 1930's getting all the Jews out of government and any influential places in Soviet economy. One must not forget the Great Starvation in the Ukrane then as well.
Nazis Germany used to do medical experiments on Jews, Russians, Gypsies as well did the Russians. You might have heard about Joseph Stalins obsession with trying to breed Gorillas with Humans to make a "super race". These are some of the diabolical things that comes from absolute power.
Yes there were differences but in practice, they were in many respects almost identical. Islam, you are 100% correct as well... just horrible....
