Any modern-day political advisor, in America or Britain or anywhere in the west, would say that going to the Muslim world and delivering a speech including the tough sentences this speech did about Palestinian violence was evidence of a political death-wish ('It is a sign of neither courage nor power to shoot rockets at sleeping children, or to blow up old women on a bus. That is not how moral authority is claimed; that is how it is surrendered').
