National Socialism was rave here in the USA under Roosevelt.
To me, the comparison is moot. The Globalist Socialist Nazi's of today wear Armani, ski in Aspen and sip Cristal.
Brown shirts had rallies in Chicago before the war. National socialism had roots in America for sure.
These rallies ended once Hitler declared war on America.
But many were initially seduced by the messenger until
his real motives were realized.
