While they did not directly mention the date, they certainly made it public what type of attack and where...from my previous post...
Then there were the predictions by an Iraqi with ties to Iraqi intelligence, Naeem Abd Mulhalhal, in Qusay's own newspaper several weeks before the attacks that stated bin Laden would “demolish the Pentagon after he destroys the White House and ”bin Laden would strike America “on the arm that is already hurting.” (referencing a second IRAQI sponsored attack on the World Trade Center). Another reference to New York was “[bin Laden] will curse the memory of Frank Sinatra everytime he hears his songs.” (e.g., “New York, New York”) which identified New York, New York as a target. Mulhalhal also stated, “The wings of a dove and the bullet are all but one and the same in the heart of a believer." which references an airplane attack.There was even a prediction in Newsweek that it would be "soon", for goodness sake...why didn't our intelligence pick up on that?
