That's exactly why us bombing Mecca is like this guy hitting the jackpot. His country is completely unaffected. But now he's got a whole bunch of citizens who are really pissed at the U.S, and therefore more united behind him. Nuking Mecca makes a guy like him stronger.
Nuking Damascas, on the other hand....
I believe there's a fair chance that even some of the governments over there that give some level of tacit support to terrorists do not want them to do something like explode a nuke. They fear our response may be to nuke them, and they don't want to take that risk. Nuking Mecca likely would generate a "phew, lucky it wasn't me" from those type of despots.
And a threat to nuke Mecca isn't helpful either, because it supports the idea advanced by the islamo-fascists that we just want to get all moslems. If the entire moslem world ever believes that we are motivated not be a desire to stop terrorism, but a desire to eliminate islam, then whatever cooperation we've been getting -- and its been substantial from some -- will evaporate.
There's a large dollop of naivete here. At this point in the process everything points to a distinction without a difference. Our real enemy is islam.
As for cooperation being "substantial", I have failed to notice any. Just pro forma busy work to be able to claim to be doing something.
To be blunt, can I challenge you to name any country which has begun closing madrassas? One? Any?
If all the cooperation we have been getting of late were to disappear, it would make no difference whatsoever in the larger scheme of things.
