The Cold War nuclear deterrence strategy known as MAD (mutually assured destruction) is now clearly obsolete. We are likely, one day, to see the use of a nuclear weapon that does not have a return address. For this new situation, we need a new deterrence strategy. I propose one to be known as MAD-AS-HELL. Under MAD-AS-HELL, the U.S. should promise the world that it will respond to a nuclear weapon detonated by an unknown agent or government and directed at the U.S. or its allies, with a devastating rain of nuclear fire on EVERY country believed EVEN POSSIBLY the attacker OR possibly the ultimate source of the weapons.
Right now, that would clearly mean that if a nuke popped off in a U.S. harbor or in Israel or Japan, for example, the U.S. would turn all of North Korea into a nuclear waste site. If (when) Iran joins the nuclear club, then two countries would get the treatment. If Pakistan in the future, with nukes it already has and a record of proliferation, should become overtly hostile to the West and unhelpful in the war against terrorism, then they would be added to the list of automatic targets. Other nations Islamic nations, in particular, such as Egypt or Indonesia, but also Venezuela could be added to the list for the automatic MAD-AS-HELL response if they insisted on playing with the nuclear big boys. Happily, we have lots and lots of nuclear fire.
There would be three benefits from this policy: (1) A country attacking the U.S. could not escape punishment merely by being sneaky in their attack; (2) These countries might start policing each other realizing that they would all suffer mightily if one rogue country (or its terrorist surrogates) attacked the U.S.; (3) Third-world countries would cease to be so eager to join the nuclear club as membership would now have severe risks, as well as prestige.
