Al qaeda is happy too!
Oh, and Dave -- yes, we are supposed to ignore it... or more accurately pay it little mind. Who cares if they think they're happy right now. They were ecstatic when they blew up 4 planes and brought down the towers. What happened a few months later? The completely lost their base of operations and were sent scattering to the winds, being temporarily operationally crippled.
AQ's understanding of American policy and actions is limited at best... blinded by their own propaganda. To give credence to their worldview is a mistake.
