AND SOMEONE INVITE CHINA. Justin Logan notes a wee problem with the proposal below, namely that permanent Security Council member China isn't a member of the G-8 so, technically speaking, "The five permanent Security Council members" can't, as such, do anything at "this weekend�s Group of 8 meeting." At any rate, China doesn't normally take strong stands on these issues, so they could presumably be brought on board if everyone else could.
It's worth mentioning here that the Bush administration has a strong interest in stepping up to the plate. The elected government in Beirut is really Bush's only real positive achievement in the region and the whole thing risks falling apart at the moment.
