I have a solution: we force the region to start respecting human rights or we start incarcerating offenders. We don't need to build a bunch of condos for the palestinians, we don't need to give them lawyers or outsource their legal disputes, we don't need to help either side militarize against the other: we just need to hold them to a bare minimum standard by force and they'll sort the shit out in a few decades.
This is what the ICJ was made for. These are the rules we all agreed to play by after WWII. They fucked around, it should be the right of anybody and everyone who wants to interfere to go in and make them find out.
BTW human rights should include not being segregated into walled off districts.
