"...The basic problem is the divergence of interest once you go beyond the shared loathing of the Tehran regime and the common U.S.-Israeli abhorrence of Iranian nukes. Since these threaten Israel’s existence, other items like oil fields in Saudi Arabia, tanker traffic in the Gulf or terror in Iraq are logically secondary concerns. For the United States, on the other hand, these “secondary” concerns are primary ones. In the war in Iraq, it matters a great deal how the Iranians would respond on that front line. Forget the Mahdi Army; even Moqtada Sadr is not a flunky for the “Supreme Leader.” But how about a straightforward lunge of the Revolutionary Guards into the Basra province—oil wells and all?
...The Israeli air force cannot stage such a three-pronged campaign. Nor would it have to because even $300 oil pales in significance to national survival. For the United States as the global power, however, Iranian retaliation in Iraq or against oil assets matters greatly. Therefore, these threats would have to be eliminated along with the Bushehr reactors and the enrichment and reprocessing plants. Hence, it is either a real war or none at all. Israel cannot be “delegated.” Nor should it be."
