What better way to get the entire Muslim world to want to kill us? These terrorists couldn't care less about Mecca. Mecca gets destroyed, all Muslims come together to fight the Americans. The end justifies the means.
And yet every suicide bomber devoutly believes his satanic end justifies the means.
Islam has flunked the 20th Century. IMO it will never recover from its barbaric self-destruction.
And if some wild-eyed, hypnotized 16-year-old thinks he will further the glory of Mohammad by blowing himself up inside a Smallville, U.S.A. second grade classroom, he'd better realize now that Americans will wipe his remnants off the face of the earth.
