Why Israel is tagged as American-side?

[Linde]

Further, this ethnicity was indeed the basis of the Nazi genocide of the European Jews.

Why only Jews were targeted? None of the Abrahamic religion was originated among European Whites, and all the major three were expansionary and practising proselytising.

The Nazis did not target Jews because of the religion.  I was, if I may say so, because of our ethnicity.  As I wrote earlier, my family lived in Germany for several hundert years, but most of my DNA is still from the Levant.  We simply did not mix with the Germans we were living with.  The Nazis wanted to eliminate the ethnicity.  They did the same with the Roma people (know as Gypsies).
