If I remember correctly, it was at least a week before AQ publicly claimed credit for the 911 attacks. Seems like their saying nothing could be a strategy to extend the terror. Once someone comes forward and admits responsibility, a fraction of the fear is reduced. Not knowing will get you every time.
Well if you’re remembering correctly.......there’s truth in what you say; the not knowing will get you every time. I don’t know why, but I thought they claimed credit for the attack within a day or 2 of the event, but I could be all wrong.
Of course, another possibility is that they took credit sooner then now because they had something resembling an intact leadership. I haven’t heard or read of any one central leadership personality with them these days since Osama is gone.
