"The threat has military significance, and it would be both prudent and appropriate for the Americans and their allies to have responded militarily — if only by “leaning forward” a bit more. The Persian Gulf is now one big game of chicken. When the Iranians get belligerent, we have to respond in kind. Iran is getting ready to expel the IAEA inspectors. The United States needs to make it clear that the expulsion of the inspectors will be considered an act of aggression, and that we will respond appropriately.
So, long story short: It wouldn’t surprise me if the British sailors were detained because the British did something to make the Iranians really angry. Khamanei dramatically upped the ante this week. We probably raised. And they probably raised back. The stakes in this nuclear-poker game just got a little higher."
