I would test a nuke in the Pacific, then send a fleet of Stealth Bombers in an arc-light formation headed towards the middle east and make absolutely no confirmation of what is in their payloads. Have them land within 30 min striking distance off the Iranian and Korean border and communicate an ultimatum to their internal armies.
Hand over Bin Laden, Mullah's and Kim Jong, or watch Mecca dissapear (a good example for Kim Jong).
