A single high-altiltude electromagnetic pulse from a nuclear detonation could do a lot of damage to the US. Launching it off the deck of an oil freighter along one of our coasts would make it hard to intercept and difficult to tell where it came from. The Iranians are just crazy enough to try a stunt like this knowing full well that MAD applies.
