Paul Krugman does an O.J.

And explains if he did it, how he would start a war with Iran:

So the administration has always had it in for the Iranian regime. Now, let’s do an O. J. Simpson: if you were determined to start a war with Iran, how would you do it?

First, you’d set up a special intelligence unit to cook up rationales for war. A good model would be the Pentagon’s now-infamous Office of Special Plans, led by Abram Shulsky, that helped sell the Iraq war with false claims about links to Al Qaeda.

Sure enough, last year Donald Rumsfeld set up a new “Iranian directorate” inside the Pentagon’s policy shop. And last September Warren Strobel and John Walcott of McClatchy Newspapers — who were among the few journalists to warn that the administration was hyping evidence on Iraqi W.M.D. — reported that “current and former officials said the Pentagon’s Iranian directorate has been headed by Abram Shulsky.”

Next, you’d go for a repeat of the highly successful strategy by which scare stories about the Iraqi threat were disseminated to the public.

This time, however, the assertions wouldn’t be about W.M.D.; they’d be that Iranian actions are endangering U.S. forces in Iraq. Why? Because there’s no way Congress will approve another war resolution. But if you can claim that Iran is doing evil in Iraq, you can assert that you don’t need authorization to attack — that Congress has already empowered the administration to do whatever is necessary to stabilize Iraq. And by the time the lawyers are finished arguing — well, the war would be in full swing.

Finally, you’d build up forces in the area, both to prepare for the strike and, if necessary, to provoke a casus belli. There’s precedent for the idea of provocation: in a January 2003 meeting with Prime Minster Tony Blair, The New York Times reported last year, President Bush “talked about several ways to provoke a confrontation, including a proposal to paint a United States surveillance plane in the colors of the United Nations in hopes of drawing fire.”

In the end, Mr. Bush decided that he didn’t need a confrontation to start that particular war. But war with Iran is a harder sell, so sending several aircraft carrier groups into the narrow waters of the Persian Gulf, where a Gulf of Tonkin-type incident could all too easily happen, might be just the thing.

As easy as that. Recognize anything familiar?
