I like the idea, but nuking a city in Saudi Arabia might not be a smart move for us to deal with. Things would have to be fairly sideways to justify that.
Well recall Nixon was planning on nuking the dikes on the Red River and flooding the valley as well as Haiphong.
Think 3000 dead in NYC and the twin towers down would be more then enough justification to show the Moon God people that they believe in a 1400 year old fantasy.
To justify it after the fact is an exercise in futility. The action would speak for itself. Then we move along from there without the Islamic threat. Did anyone cry for the Axis? Everyone fears the bully until he is toppled and then everyone sighs in relief. This has been going on for 1,400 years. It is time to end it now with the press of a button.
