It doesn't make sense to abandon Israel from a western military point of view. They're the proxy in the war against the middle East (namely Iran) and losing that would end up harming western interests.
This whole war has never been about Palestinians, they never would have had the funds to fight Israel on their own. It's all been money funneled from Iran and other anti Israeli countries into Hamas or one of the other terrorist groups in yemen or Syria being used to attack Israel.
Google Iran Israel proxy war, I'm not making this shit up.
Always ask where the money is coming from, in every situation.
