The minor nuclear powers - and I include North Korea and Pakistan in that category - can be attacked and their arsenals destroyed, but only if we have the will to do the necessary damage. That would involve either earth-penetrating nuclear or non-weapons delivered by our stealth bombers or nuclear attack on their facilities delivered by ICBM or cruise missiles. In either scenario, there will be fallout, literally and figuratively. However, it will make unambiguous the fact that we will not tolerate additional nuclear powers - least of all rogue ones - and that, more importantly, simply possessing nukes will not deter us from dealing with these outlaw regimes. The alternative would be for us to shut up and simply live with the nukes.
