Jay Nordlinger sums it all up very well on The Corner:
It would be helpful to peace in the Middle East if Israel’s enemies could be absolutely sure that Israel is not going anywhere: that it is here to stay. Remember the old gay slogan? “We’re here, we’re queer, get used to it”? Israel’s enemies need to know something like that about Israel. But as long as they have the feeling that the world — you know: “the world,” as in the New York Times, the U.N., and Bono — is not really committed to the existence of Israel, they will push for Israel’s destruction.There really is no getting round the core problem. It has to be solved because Mr Nordlinger is right in saying that there will be no peace in the Middle East until Israel's existence is accepted by all, not just Egypt and Jordan.
They have never resigned themselves to Israel’s existence; they have never resigned themselves to co-existence. People like Helen Thomas make it easier for them not to resign themselves. People like Thomas give them hope — making them think, “Ah, maybe we can actually get rid of them. Not just extract a better deal, but get rid of them altogether!”
Of course, shutting Bono up would help as well.
