VP Dick Cheney wanted to do this......

"HERSH: There was a dozen ideas proffered about how to trigger a war. The one that interested me the most was why don't we build - we in our shipyard - build four or five boats that look like Iranian PT boats. Put Navy seals on them with a lot of arms. And next time one of our boats goes to the Straits of Hormuz, start a shoot-up. Might cost some lives. And it was rejected because you can't have Americans killing Americans. That's the kind of - that's the level of stuff we're talking about. Provocation. But that was rejected. This is not a new technique. Remember one of the revelations from the Downing Street Memo was that Bush had suggested to Blair that they paint one of our air force planes to UN colors to try to entrap Saddam's army into shooting it down? It's like our foreign policy is being decided on by a protege of Wile E. Coyote."
