The neoconservative Bush administration will attack Iran with tactical nuclear weapons, because it is the only way the neocons believe they can rescue their goal of US (and Israeli) hegemony in the Middle East.There is already talk of retaliation by Iranian attacks on US warships and troops across the Persian Gulf and major Iranian interference with Shia communities in Iraq and Bahrain if this happens -- not to mention the possibility of an attack (probably terrorist) on US soil. At least this is what is being talked about in Iran specialist circles.
The recent North Korean nuclear test must have changed the approach to Iran considerably -- clearly if you are against Iran developing nuclear weapons (which most estimates say won't happen for five years to a decade) you would think that the earlier you strike the better. North Korea shows that if I you can develop nuclear weapon, you should and that there's little that can be done about it -- especially if your neighbor/patron is China.
The article has some small factual mistakes and exaggerations -- "Our Egyptian puppet sits atop 100 million [sic] Muslims who do not think that Egypt should be a lackey of US hegemony" -- but gets the general regional situation quite right. I remain skeptical on whether a tactical nuke would be used, even though the Bush administration's military doctrine has emphasized the use of tactical nukes for five years now, but I do find something convincing in the argument that the Bush administration, by its own internal (and electoral) logic, has nothing left to do but escalate. It either stands down or muddles along with a recognized failure in Iraq, or ups the ante. Rien ne va plus.
