There would need to be real truth and reconciliation hearings where those who did evil, on both sides, could be held to account for their actions.
Funding lots of money in order to have thriving industry and jobs. The level of unemployment is Gaza is mind-blowing.
It would take a process of decades. There would have to be a real opportunity to elect real leaders not born of fear and anger, but hope and opportunity.
Eventually, that would involve a real armed force, but that would be something like how America treated the Japanese after WW2. There would need to be constraints. I also see a DMV that would be secured by peacekeepers at first and then both sides.
