The PA is generous but foolish in offering the Green Line as the (basis of the) border. Whatever Israel's emotional and historical wish-dreams, it is not legally entitled to ANY land beyond its May 1948 border. Why should it profit from illegal land seizure, entirely contrary to international law? With any other nation, Abbas's generosity would be recognised and would help to bring negotiations to a speedy and successful conclusion. But not with Israel. Give them an inch and they take a yard (or three). Are they happy to be offered this extra free land that they don't even have to PAY for? Nope, not at all, they already take it for granted, pretend to believe that they are somehow entitled to it and even want ANOTHER 7.5-8.5% of Palestine on top! (As well as wriggling out of compensating refugees, etc.). The PA is being far too soft on this. When dealing with snakeoil salesmen, it is best to start by giving NOTHING away up front.
