A lot of those Arab “Christians” are culturally Muslims
You are correct, I have said before and will say again there is one bridge, a conduit of agreement between the Eastern Church and the Muslims, they both hate the Jews, always have, and likely always will.
Then God asks, why?
Well, God doesn’t need to ask, that is just a flourish, God already knows of course, and the Jew haters will face Him in the end.
