I think trying to get peace in the middle east is impossible. Since the dawn of time these people have been killing each other. With that mindset these people do not know peace. But if you do beleive the Bible (which I am sure there are a few here) then you will see the prophecy of the 7 years of peace. This is such a big deal to that regions since it has never had peace for so long. The person that puts that treaty together is said to become the anti-christ after suffering from a fatal head wound. So what I am saying is if you want to bring peace to the middle east, be prepared to become the anti-christ.
but seriously it is pointless to think that we can do anything to stop these people from killing unless we stop them first, they will never be happy and if we were to back off the pressure it would only encourage them more cause we would be showing signs of weakness.
