Ahmadinejad's return of hostage British sailors as a "present" for the Easter holiday to the "British people" demonstrates two irrefutable truths: (a) Blair was right not to give in on a single point; (b) Ahmadinejad is utterly inept and is flailing about, trying to find some means to gain prestige abroad and legitimacy at home.
Our only regret is that the intrepid Brits were also the polite Brits on departure. Their consent to the smiling, waving photo op seen here, apparently after a quick trip to the suit department of the Tehran Sears and Roebuck, speaks volumes about the polite folkways of their culture but nothing about the creepy reality of the situation. Iran remains a country ruled by wing-nuts, and incompetent ones at that.
So let's keep up our staring contest with them. A blinking wing-nut is safer than an unblinking one. And sooner or later, the internal contradictions of the "Islamic State" will lead to Iran's collapse as a threat, no less than the same happened for the Marxist Soviet Union.
