A Michael Totten interview with Martin Kramer;

Iran wants to create uncertainty there because oil is the only thing it has. Iran has nothing else—some carpets and pistachio nuts, and that’s it. Their population continues to grow, their needs continue to grow, and their grand ambitions continue to grow. So this, I think, is the first thing they would do with it. All it takes is to create a crisis or a succession of crises.
Iran knows it can’t wrest sole hegemony in the Gulf from the United States, but it wants to create a kind of dual hegemony shared with the United States. Nobody knows where the lines would run, but they wouldn’t run just five to ten miles off the coast Iran into the waters of the Persian Gulf. Iran would like to see its share extend to both sides of the Gulf, to effectively create a kind of push and shove between the United States and Iran.
A lot of people on the Arab side of the Gulf will say they feel Iran’s breath on their faces. The United States is there now, but the British were there once, too, and now they’re gone. The Persians are always there and will always be there. So we’ll see a lot of hedging. Iran would be perceived as the rising power and the United States a declining power.

Canada’s smartest columnist misses the point.

From a practical standpoint, Williams’ concern is misplaced. The perpetrators of most high-profile terror attacks of the past decade were Muslims who weren’t in “Muslim garb,” who weren’t outwardly “identifying themselves first and foremost as Muslims.” […] They went to strip joints and wore khakis rather than flowing robes and head scarves.

Or; “Khakis didn’t fly people into skyscrapers. Muslims did.”
