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.
Sadly that would not happen. We would be singing "We Shall Overcome" and ask why they don't like us.
Maybe they don't have a nuke, but a disaster of 9/11 porportions is certainly going to happen again sometime in the future, probably again as a result of illegal immigration. Remember, the 19 9/11 hijackers had 63 drivers licenses between them and we all on overdue visas.
If we are hit again and it is found that the perps were here illegally on some overdue visa or crossed the Mexican border, I will be the first to call for GWB's impeachment for deriliction of duty.
That's fine with me, but we have to clean our backyard first, purge towel heads from our homeland.
