Thomas Barnett’s got about the most clearcut, incisive rundown of the strategic reality we face in terms of Iran that I’ve seen to date. We can’t afford to be naive about Iran’s intentions. But neither can we afford to be naive about our own leverage, which are tactically diminished right now. That means it’s time to start thinking about the long play. So, sure, containment (as opposed to isolation), but combined with engagement. The fact is, the only things that even raise Iran to the level of irritation are its location and its oil reserves. That’s two major factors to consider, but contrary to what Liz Cheney would have us believe, time is definitely on our side.
