We need to make it absolutely, perfectly clear. A detonated nuclear device in the US by islamite fanatics will be the end of Mecca and/or Medina. Let the other islamites deal some restraint.
If a nuke goes off in a US city - nuking Mecca and/or Medina is not nearly enough in response. There better darn well be smoking glass craters all over the middle east and beyond within hours of the event. At that point playing nice is out.
I guess it would take something on that scale before some of the Democrats would not say solve the problem thru diplomacy.
