Nazism was very much in favor in America previous to WWII as the Zeppelins casually crossed sea to shining sea with the Swastika on its tail. FDR was very slow to acknowledge the Holocaust and America very well could have stayed neutral during WWII against Germany. This typical Jewish virtue signaling is so tired and old.
FDR wanted war with Germany, his "Arsenal of Democracy" talk was, for all intents and purposes, a Declaration of War on Germany.
