LH, from my perspective, Judaism, Christianity, and Islam are all just branches of the same big religion. I find it very strange that they can't see that themselves. It's also strange how angry some members get if it's pointed out to them. But it's not the descendants of the ancient Israelites who are fighting with the Arab descendants of Abraham (as I know you are aware). It's the descendants of people who were converted to Judaism from other (probably Pagan) religions who are doing most of the fighting with the non-Jewish Arab descendants of Abraham (many of whom are descendants of people who converted to Islam and Christianity from Judaism). So I don't think it can really be characterized as a family squabble in that sense. As you know, the real descendants of Abraham who remained Jewish in the Middle East had no difficulty getting along with those who were not Jewish until the descendants of the European converts showed up.
