Ending apartheid, giving the common everyday civilian a future they can build toward, hope for, and participate in. Give people no hope, and they will lash out.

Having a secular government in the region, not a theocratic one, would go a long way to maintaining equality and joint prosperity.

Nothing buys forgiveness like mutual economics.

Forever war. Back in the day, the stronger side would just kill everyone in a march to the sea, salt the earth, and nothing would grow there for 300 years until humans finally scraped the dirt and made a small community again. It’s been happening over every religious war, every empire, and every tribe for all time.

Now, we don’t do that. But that means bad blood and prolonged conflict essentially forever, in a long simmering he said/she said involving beheadings and rockets. Best thing we can hope for is either a Korea situation, or some sort of “we’ll make this area into a national park where everyone can visit”, but neither side wants to live anywhere else, and hell will freeze over before all the Palestinians or Israelis are welcomed into the neighboring countries with open arms, lol.

My last bit of hope died when I learned that Hamas executed one of their generals on the rumor that he might have had sex with a guy. The fact that they stripped someone of their 1,000 person command, whipped him, forced him to not sleep, and then shot him three times over something so trivial is a really, reallllly bad sign for any hint of a two state solution. Or worse, cohabitation in a host country. They hate each other to an extreme I didn’t think was possible.

Other than completely eradicate one side off the face of the earth, I guess nothing.

Israel and Palestine (+Muslim world) hate each others.

Religious conflict has only taken hold in the Middle East because SOME PEOPLE overthrew all of the (more) secular left-wing governments and replaced them with right-wing theocratic regimes.
