Who will Israel negotiate with, if Hamas was gone?
Then they would negotiate with a relevant Authority that would be set up. But that’s completely moot as Hamas is not gone, are not going and will not go no matter what. Until then, they will disrupt any such Authority, or attempt thereof. It’s also questionable who the Palestinian populace would throw themselves behind in this regard given the support for Hamas. So, who will they place their trust in, an Authority they may not want, or a group they support? If they thought it through, they’d jump on the current wagon, give lip service to a new Authority to solve the immediate problem, then once established, work to wiggle Hamas back into it. Then it all starts again.
There needs to be a permanent solution. I don’t know what it is. I suspect it’s a ‘very be person must move out’ thing - my analogy is, you can never have divorced people who don’t like each other sharing a home by agreeing to use different rooms, and expecting it to be peaceful for longer than 5 minutes. Same here. So, who moves, and where to, really. I have nothing to do with either side, no background, friends or family with either, but it’s only ever going to be truly solved by one person moving out of the house I suspect. I’ve truly got no preference on who that would have to be.
ETA - anyone ever watched that movie, think it was War of the Roses (or something similar) with Michael Douglas and someone Turner. Watch it and call one of them Israel and one Palestine. Same situation but then just think if the house as an area of land.
