Time for a Nuclear Strike Doctrine
It's time to dust off literature on nuclear doctrine. We have to be ready, just in case the actions to keep nuclear weapons out of the hands of Iran fail. Those measures should, by the way, include the option of massive air strikes against these facilities in Iran.
The nuclear doctrine towards Iran and similar countries must be absolutely clear. If they ever, under any circumstances, use nuclear weapons will their own country be hit with a massive nuclear strike effectively eliminating their country.
The response will have to be automatic. There will be no questions. No rounds in the UN. There will be no consultations with allies or adversaries. The response has to be an immediate and unconditional consequence.
And we'll better get used to the idea to, once again, use this horrible weapon. This will produce extreme suffering and destruction but there is simply no other way to respond in a fashion that may prevent it from ever happen.
