Deputy Defense Secretary Paul Wolfowitz sends a memo to Defense Secretary Donald Rumsfeld raising the possibility that Saddam Hussein played a role in the 9/11 attacks. In the memo, titled “Preventing More Events,” he argues that if there is even a 10 percent chance Iraq was behind 9/11, maximum priority should be placed on attacking Iraq. But he contends that the odds are “far more” than 10 percent. He also cites a controversial recent book by Laurie Mylroie which argues that Iraq masterminded the 1993 bombing of the World Trade Center (see October 2000).
