Commonly forgotten in history is the fact that BOTH the Third Reich and the Soviet Union started WWII together. The Germans did not invade Poland all by themselves.
As for the horrors of the Holocaust, also commonly forgotten is the fact the Soviets slaughtered at least as many Ukrainians as the Nazi slaughter of Jews.
The most amazing thing is that American Communists and fellow travelers spewed out propaganda in books, columns and films against "fascism" with unrelenting relish during the Spanish Civil War and thereafter. When they got their marching orders from uncle Joe on the day the Ribbentrop-Molotov was signed, they suddenly became pacifists, calling US aid to Britain and other countries opposing Hitler "criminal" and "imperialist."
Naturally, in June of 1941, they turned on a dime, demanding America send billions of dollars in aid and millions of her sons to rescue their beloved Stalin.
A reminder to FReepers that Russia's denunciation of "Nazis" [in Germany, Ukraine, or anywhere else] is usually a matter of propaganda, and certainly never one of historical accuracy:
Not a glass house the U.S. should be throwing stones at.
For several years leading up to WWII, democrats in America held NAZI rallies in such places as Madison Square Garden. They would flock there by the thousands, many wearing NAZI uniforms and NAZI flags were hung with honor inside.
FDR even liked the NAZI brand of socialism vs the communist version.
So, fascism wasn’t defeated will the fall of NAZI Germany, it survives here in the USA in the National Democrat Socialist Workers Party, aka DNC.
