If this is Ahmadinejad's bluff, it is bluff worth calling

"Iran is a complex and sophisticated nation that offers more plausible diplomatic pressure points than ever did Saddam's Iraq. While Ahmadinejad may eat, drink and make merry on the Pentagon's ineptitude, he must look warily over his shoulder at his boss, Ayatollah Khamenei; at Iran's national security council under the more temperate Ali Larijani, whom Ahmadinejad does not control; and at his old foe, Akbar Rafsanjani."
