The Endless War With Iran

As pressure mounts for a U.S. attack against Iran's nuclear capability, bloggers at the National Interest, published by the Center Previously Known As Nixon, wonder when the war would end:

How do attack advocates propose to stop the Iranian nuclear program if Tehran refuses to roll over after one round of attacks? There are two logical responses to this question. One is regime change, presumably through invasion. But there are significant downsides to invasion, not least that such a war would likely prove protracted and costly... The other is that the United States should be prepared to conduct repeated strikes over a long period of time to ensure the Iranian nuclear program is kept down.
