What I'm arguing for is an Iran policy of "creative opportunism." We should take advantage of the fact that our biggest adversary in the Middle East has just had a political crackup. President Mahmoud Ahmadinejad's vote-rigging putsch has backfired. Supreme Leader Ali Khamenei's attempt to squelch protest has only revealed his weakness. In the post-election turmoil, even Ahmadinejad and Khamenei have been squabbling.
