There is no material cure for the Palestinian death cult Bushido and its war of return until its adherents feel totally isolated with no--as in zero--international support.
The Marshall Plan worked because it was preceded by TOTAL apocalyptic Gotterdammerung defeat. Nothing less will suffice to uproot the jihadist shaheed death cult that defines the highest calling of a Palestinian to be killing Jews. I make this point here:
You totally underestimate what it takes to deprogram brainwashed human minds from addiction to victimhood and looking the mirror and admitting you screwed up and are defeated with no do-overs.
Some problems have no solution and can only be managed and mitigated. Listen to Dan Schueftan: https://www.youtube.com/watch?v=VH3-h44VRrQ&t=1s
