Well, so far it has in fact stopped at the Twin Towers and since we have not broken up the "little gang of thugs" that perpetrated 9/11 but in fact made them bigger and stronger, it seems you do not know what you are talking about.
I agree! The very idea that we should cooperate to stop terrorist is totally stupid. The best thing to do is wait them out. Maybe they will go away when they see that its just fine with us that they kill us all.
