Re: "...Bottom line is the Palestinians walked away from a deal that would have given them their own nation..."
You are right, nobeach, the Palestinians did walk away from a good deal at one point but the bottom line is that there is gross and callous manipulation of mindless rage on both sides resulting also in great suffering on both sides.
Israel ceded Gaza and the West Bank to Palestinian control. They elected a terrorist group, Hamas, as their leaders who immediately slaughtered their palestinian political rivals. Ham as has NEVER moved away from it's belief that Israel should not exist.
First step to peace is recognize the state of Israel and confirm it's right to exist.
