Does Libya set a precedent? If a revolt breaks out again in Iran, and the regime cracks down with brutal force, will the United States support a Libya-style response? Is there an Obama Doctrine" emerging? It looks like it. It appears that Obama is ready to use U.S. military force anytime, anywhere, for any reason that he - without Congressional approval or UN support - deems legitimate. During the course of the "War on Terror," now a decade old, there has been a constant barrage of efforts to disparage those who called Iraq, or Afghanistan, a "war for oil." It's not bizarre at all to argue that what animates nearly the entirety of American policy toward the region from Algeria to Iran is concern about oil and natural gas. That's been the driving force behind the creation of the Rapid Deployment Force by President Carter, the establishment of Centcom by President Reagan, the invasion of Kuwait by President Bush I and America's arming of Saudi Arabia and the other members of the so-called Gulf Cooperation Council. It's why Obama muses about "maintaining the flow of commerce" by military means. Which brings us to Iran. If the anti-Ahmadinejad forces rise up again, and perhaps take control of a city like Shiraz, or if Iranian oil workers strike and take control of a southern oil city such as Ahwaz, ... the regime would crack down brutally. And then what?
