The POS's that did this will burn in hell, lets just make sure we don't join them by jumping the gun. We don't need to waste our time hunting down the terrorist's, or money leveling a continent. We need to commit both to putting the countries funding these walking bile infections on their knees and showing them who their daddy is. Their "holy war" of terrorism and barbarism just stepped up to an act of war on the most powerful country in the world.
As the sole superpower we our forced to take the brunt of the blame from the enemies of those we help, and yet still act humanely when we are accorded no such courtesy. This supposably happened because of our activity in the ME. Guess what? Because of this we just became a whole lot more active, and pissed off to boot. Let's just hope Bush doesn't decide to play General.
As for warning, Bin Laden threatened an attack in an interview not to long ago, and the Palestinians (Though claiming innocence.) have said to consider it a warning.
I pray that those who perished enjoy a life beyond the pearly gates that overcompensates for their cowardly murder.
