You would also need someone on the Palestinian side that the Israelis would trust to keep their word and not attack. That trust just isn’t there and will be difficult to rebuild.
I’m not completely disagreeing with you. The illegal settlements need to go. I’d like to see any illegal settlements responded to by having a special group of Israeli police, working with Palestinian authorities and not just moving in on their own, arresting the settlers instead of the military moving in to protect them.
There’s also the outside influence to consider. Evangelical Christians love the settlers. They help them and any politicians who would protect them. They’d work against a politician who promised to arrest them.
There are a lot of factors in play and the solution won’t be an easy one.
