"I don`t think "force" would be necessary. Palestine and Israel are representative democracies - result of unpopular agreement is defeat in election." Yes. If a party still wants to play the game of democracy. Extremists like Islamic Jihad who won't wield much power via the democratic process will likely prefer the alternative of armed resistance, even after a peace deal. Which is why they will also have to face arrest and prosecution if it comes down to it. What will Hamas, who does wield political power, do? Hard to know. That said, I agree Israel must go the bargaining table prepared to make serious compromises. And with your overall hypothesis that giving hope undermines the appeal of violence.
