US and Iran: The best of enemies?

In this episode, Empire asks if US-Iranian relations have taken a turn for the worse. The time for hands extended in friendship has been replaced by menacing fists, as both sides ratchet-up the rhetoric. Will this mini cold war continue, giving both the US and Iran time and face to get back to the negotiating table, or will the bellicose words lead to a confrontation that neither side wants? Empire finds out.
