This plan will absolutely be another waste of time without tangible results regardless of whether it gets signed by anyone.
This is a Kushner hobby at taxpayer expense.
I would wait until the actual plan is revealed, for three reasons:
1. The leaked plan may contain several trial balloons to test Israeli and Pali and other reactions.
2. Everyone I’ve talked to who knows more than I do about the situation there swears that the plan that was leaked is fake, that it can’t possibly be the real plan because it is totally unacceptable.
3. There are other political reasons why a completely false plan could have been leaked by those from Netanyahu’s opposition.
4. It is possible that the volatile situation that obtains right now in the Middle East will have to get worse before a peace plan is agreed to, and the creators of the plan know this. Thus the delays.
