It’s certainly a different approach.
Some of observations:
$50 Billion from the Arab countries for the Palestinians sounds encouraging. Is it enough for the Palestinian buy in? Not the amount so much as the incentive of cash versus political and religious differences.
The Palestinians have 4 years to accept or reject. That seems like kicking the can down the road, but with a detailed plan rather than goals. Elections in both Israel and the US for leaders under pressure seem to provide incentives.
The map looks like a Republican district in Virginia, but may be a starting point because it does provide a contiguous border. Sort of. It needs a long tunnel to work.
I think the hardest buy-ins are the existing settlements within the Palestinian territory. That would be like giving Mexico control over a few dozen towns in Texas. On the other hand, it could lead to better relations if the orthodox on both sides don’t screw it up. Leap of faith required.
I am sure that since this just came out unilaterally, there will still be a lot of negotiations to come. Which puts this in the same category as past agreements. That is, we are seeing the first offer, not a deal. Counter offers to be announced.
