Nationalism is the belief that the world should be divided into ethnically-homogeneous nation-states. So it’s perfectly consistent for nationalists in one country to support other nationalist states outside their own.

American Christians have always had a complex relationship with Judaism. On the one hand the American sentiment toward racial, ethnic, and religious purity is deeply ingrained and an important control mechanism for the corporate aristocracy. On the other hand it’s very clear that textually they don’t get heaven if Jews don’t control Jeruselem and rebuild the Jewish temple… again. How they square this tension is individual. Most don’t know or care that it’s a self-contradictory position. Of those who know, most do the “God works in mysterious ways” thing, and there’s also a menagerie of different smaller attempts to rationalize it, only a few of which include actually discarding racism. Ultimately it almost always boils down to a contradiction though, so yes, fundamentally, their answer is hypocrisy, or just ignoring the conflict altogether.

The return of Christ and the Rapture depends on Israel, according to the story. I don’t know the details. But that’s how they can not like Jews, but want to support Israel.

The doublethink is part of it but American Christians are famously uneducated in their own religion and they feel a debt to what they see as Christianity’s originator and ally against the heretical Islamists. Mix all that up with a media industry disproportionately ran by Zionists and you’ve got the current conundrum.

You are asking for rational thought from irrational people.

“We’ll deal with the jews again when the arabs aren’t an effective scapegoat anymore”

Is my wild stab at their reasoning.
