Why Israel is tagged as American-side?

[Linde]

[... is partially settled by Jews from European countries [...]

Great answer Linde, and there is no "but" to it, either. I just want to point out an issue, which is that the "Palestinian" Arabs falsely claim the Jews are European invaders to the land of Israel, yet it should not be forgotten that the Jews arrived in Europe from the land of Israel and thus mostly, have Judean heritage ! 
Further, this ethnicity was indeed the basis of the Nazi genocide of the European Jews.

And this is a fact.  Most of my DNA is from the Levant and Northern Africa.  I have a bit of Iberian and some northern European DNA.  My family lived in Germany for several hundred years, but remained pretty much a people from the Levant (DNA  wise).
