I'm going to avoid giving them clear motivation for why they do this

I won't pretend to understand the Zionist motivations at work here - except maybe that they think they can harness the Christian psychosis to achieve their own ends - but I can tell you exactly why a bunch of Christians support this shit. They, like Mike Flynn and this other guy subscribe to a wild, apocalyptic version of Christianity, and they literally believe that a world war based around events in Israel will herald the coming of Christ.

So it's actually good to support horrific war in that area, because it means that soon Jesus will come and fix everything.

This is the actual stuff I was taught as a child. This is what my parents believe. War in the middle east is good because it could bring Jesus.
