Wow. Am pretty sure that if US President Barack Obama wanted peace, he could bring Netanyahu to the negotiating table within a week, end the Iseali military forays, and cause a massive shift away from apartheid policy.
All he has to do is call up Netanyahu, and say, "We're looking at this Divestment & Sanctions campaign."
It would all be over, right then and there. It would become an abstraction, fought by lobbyists. The thousands of dead bodies would be replaced by damaged political careers.
