I saw Carter last night on three different appearances, PBS, CNN and NBC (I think it was).
Carter's analysis of the centrality of the Palestine/Israeli issue to Muslim anger and to peace in the middle east is, of course, Tony Blair's position as well. It is also the position of many American analysts and officials with experience in that section of the world. It is also the position of the majority of Israeli citizens, by consistent poll.
But it will be the case that LSM and, I'd guess MC as well, have never read Israeli publications, including Ha'aretz, Israel's leading newspaper (you can read today's issue
HERE. They won't have read Israel's great reporters/writers such as
Ari Shavit. They won't have much of an inkling, if any at all, of the size of the peace movement within Israeli society, of Israeli court decisions on treatment of prisoners, the illegal occupation of Palestinian lands, etc. They are likely quite unaware of how many UN resolutions Israel stands in violation of, offering up similar legal grounds for those forwarded to invade Iraq.
Until they get themselves educated on these matters (and I expect that won't happen) I don't know what use arguing with them might be.
