Every single family in the Israel/Palestinian Territories is matched up with a family of the opposite persuasion. One week out of every four either the husbands or the wives swap places and live with the other's family. That'll teach 'em who's human. Single people swap dwellings and jobs.
Sexual relations PROHIBITED during the swap. No one gets taken advantage of!
Israeli soldiers and PLA-type fighters are forced to take communal showers and prepare each others' food. And give each other foot massages.
Anyone not accounted for? Oh, yeah, orphans must be adopted and receive personal round-the-clock care from politicians on both sides. That'll keep the stuffed-shirts busy and out of trouble.
Crack UN troops roam the land with large-caliber Custard Cannons to enforce these edicts. Anyone caught cheating spends 6 months in Bosnia disinterring bodies from mass graves. Alternate sentence: 6 months caring for mutilated orphans in Rwanda and the Congo.
If wishes were fishes... sigh.
