By dropping the Iranian nuclear threat and shifting to the threat to the strait, Bush moves the Iran issue from being one involving the United States and Israel to being one that excludes Israel but involves every oil producer in the region. None of them wants this to happen, and all of them must take the threat seriously. If it can establish the threat, the United States goes from being an advocate against Iran to being the guarantor of very real Arab interests. And if the price Arabs must pay for the United States to keep the strait open is helping shut down the jihadist threat in Iraq, that is a small price indeed.
This puts Iran in a tough position. Prior to the issuance of the NIE, the Iranians had shifted some of their policies on Iraq. The decline in violence in Iraq is partly because of the surge, but it also is because Iran has cut back on some of the things it used to do, particularly supporting Shiite militias with weapons and money and urging them to attack Sunnis. It also is clear that the limits it had imposed on some of the Iraqi Shiite politicians in the latter’s dealings with their Sunni counterparts have shifted. The new law allowing Baath Party members to return to public life could not possibly have been passed without Iranian acquiescence.
