Certainly the Jews have a claim on "indigenous", but I think so do the Palestinians also. Though, as you said previously, the two-state solution isn't going to happen any time soon (i.e. probably never...I think the Palestinians will be driven out, possibly within my lifetime).

However, a lot of the xian nationalists support the Jews.

Yes, the Palestinians also have a valid claim to be indigenous to the area. Which is why the UN plan for the area was Partition - like India and Pakistan.

As for the xtian nationalists, they support Jewish territorial claims in the Middle East - which is not the same as supporting the Jews (a distinction that sometimes eludes DJT as well). As noted above, there are lots of distinct anti-semitic beliefs out there. One can believe (falsely) that Jews are a pernicious scourge on American society and culture while simultaneously hoping they drive the Arabs out Judea.

Again, Jews tend to thrive in a society with a strong commitment to a secular government, that values discrete minorities without pressuring them to assimilate to majority norms, and that emphasizes the norm of acceptance and tolerance over cultural or societal purity. Which are generally more left-wing, rather than right-wing, values. Which is why efforts to peel off Jewish voters over Israel (or a "snub" of Shapiro) are unlikely to be successful. Many older Jews in America are quite repelled by some of the discourse surrounding Israel, but they're not going to start voting for the party that more strongly centers Christian identity....
