That is why I think that when, in the spirit of shouting out the name of "Allah", one goes and blows up an innocent baby nearby, this cannot be citing the "God" we all know, but must be of Satan. At the risk of paraphrasing Hugo Chavez, "I smell sulfur" whenever I hear that "Allahu Ahkbar" in the jihadist tapes and then watch them blow innocent people up into small bits for no rational reason. Yep. It is of Satan. No doubt.
Osama bin Laden’s chief goal, was to bring the US into a war with Islam. He understands his own people's obligation and commitment to overcome the West and bring about a Caliphate. If we as a nation and a people, do not grasp the significance of our enemy's purpose, and why they fight on, our troubles will continue to mount, with no end in sight.
