General Chuck Wald has an op-ed on the viability of a US military strike against Iran in the Wall Street Journal today:
In a policy address at the Council on Foreign Relations last month, Secretary of State Hillary Clinton said of Iran, "We cannot be afraid or unwilling to engage." But the Iranian government has yet to accept President Obama's outstretched hand. Even if Tehran suddenly acceded to talks, U.S. policy makers must prepare for the eventuality that diplomacy fails. While there has been much discussion of economic sanctions, we cannot neglect the military's role in a Plan B.
There has been a lack of serious public discussion of the military tools available to us. Any mention of them is either met with accusations of warmongering or hushed with concerns over sharing sensitive information. It is important to discuss, within legal limits, such a serious issue as openly as possible. Discussion strengthens our democracy and dispels misinformation.
The military can play an important role in solving this complex problem without firing a single shot. Publicly signaling serious preparation for a military strike might obviate the need for one if deployments force Tehran to recognize the costs of its nuclear defiance. Mr. Obama might consider, for example, the deployment of additional carrier battle groups and minesweepers to the waters off Iran, and the conduct of military exercises with allies.
If such pressure fails to impress Iranian leadership, the U.S. Navy could move to blockade Iranian ports. A blockade-which is an act of war-would effectively cut off Iran's gasoline imports, which constitute about one-third of its consumption. Especially in the aftermath of post-election protests, the Iranian leadership must worry about the economic dislocations and political impact of such action.
Should these measures not compel Tehran to reverse course on its nuclear program, and only after all other diplomatic avenues and economic pressures have been exhausted, the U.S. military is capable of launching a devastating attack on Iranian nuclear and military facilities.
