Isn't that how it happens always? first, the parties come up with a catchy prescription for peace: one side must do A, B and C, then X, Y and Z happen. In the meantime, the other side - the more powerful one, - just needs to do AA. All looks real easy, until it comes to implementation. This is where power speaks because now A, B and C are interpreted narrowly with precise yardsticks and measurement rubrics. But mysteriously AA leaves plenty of room for equivocation and is eventually all but forgotten in the malee. I believe this is when the mathematicains and rigid policy makers should be sent home and some creative negotiation artists be brought in. Whether that happens depends on whether both parties + their outside handlers are, in fact, ready. It's like in a messy divorce with lots of kids on the line. When the parties are willing to really consider the kids' best interests rather than just say so, then amazingly, agreements can be made, even if none of the lawyers are 1st class..
