Now, smuggling a warhead or six into the US? I think that, while difficult, is probably far more feasible.
They had the capability to pull off 9/11.
I'm sure this is in the works, even if they get 1 city it's one city too much. They don't respect us enough yet, I don't understand why we're so restrained, we're not impressing anybody.
Theoretically, now don't take this as a "nuke the ragheads" rabble rousing question, but:
9/11 They destroyed a National Symbol (WTC) and tried to destroy the Pentagon and the White House and killed 3,000 civilians.
Theoretically:
After 9/11 we detonated a nuclear warhead on Mecca, destroyed one of THEIR symbols and killed 30-300K of THEIR civilians.
Do you think that would have sent a message and slowed down their momentum and made their people turn against terrorists or do you think we would be in worse trouble?
