Thanks for bringing that up and for the link. But I still think that the contemplated attack on Iran, much more than the invasion of Iraq, is mostly for Israel's benefit. So maybe the main determinant of how this goes is whether the "traditional" US foreign policy elite will be able to overcome the neocons:

A titanic power struggle is being waged within the policy elite or power elite, or more simply the U.S. ruling class. The clash is taking place over the war on Iraq, U.S. policy toward Israel--and ultimately over the best way to run the U.S. empire. The war on Iraq is shaping up as such a disaster for the empire that it can no longer be tolerated by our rulers in its present form. The struggle is as plain as the nose on your face; nevertheless it draws little comment...

This struggle is in no way hidden and definitely not a secret conspiracy. It is out in the open, as it must be, since it is in great part a battle for the hearts and minds of the American public. This fact makes the absence of commentary about it all the more chilling. The fight among our rulers sets the neocons against other very important elements in the establishment: the senior officer corps, represented by Jack Murtha and Colin Powell; the old money like Ned Lamont; the oil men, like James Baker (With Baker against the war, how then can oil be the only reason for the war?); those who want to see the American imperium run effectively, like Lee Hamilton and Robert Gates of the Iraq Study Group; many in the CIA, both active duty and retired; policy makers like Zbigniew Brzezinski who has long opposed the war which he has ascribed to the influence of certain "ethnic" groups; and even former presidents Gerald Ford who kept his mouth shut and Jimmy Carter who has not and whose frustration with Israel and the neocons is all too clear in his book "Palestine, Peace Not Apartheid."
