Deputy Defense Secretary Paul Wolfowitz asks the CIA to look over the 2000 book, Study of Revenge: Saddam Hussein’s Unfinished War Against America by Laurie Mylroie, which argued that Iraq was behind the 1993 bombing of the World Trade Center (see October 2000). Wolfowitz will mention shortly after 9/11 how he asked the CIA to do this, but it is unknown what their response is. Presumably it is not one Wolfowitz liked. [9/11 Commission, 7/24/2004, pp. 559] Wolfowitz also asks Thomas Wilson, director of the Defense Intelligence Agency (DIA), to have his analysts look at the book. The DIA is unable to find any evidence that support the theory. [Isikoff and Corn, 2006, pp. 76] Around late July, the US reopens the files on WTC bomber Ramzi Yousef, presumably in response to these requests (see Late July or Early August 2001). But no evidence will be found to support Mylroie’s theory that Yousef was an Iraqi agent. The 9/11 Commission will conclude in 2004, “We have found no credible evidence to support theories of Iraqi government involvement in the 1993 WTC bombing.” [9/11 Commission, 7/24/2004, pp. 559]
