Stephen F. Hayes examines the evidence for a connection between Saddam Hussein and September 11. The evidence doesn’t conclusively show a connection, but they don’t disprove one either.
We know at least one Iraqi agent, Ahmed Hikmat Shakir, was present at a Qaeda meeting on January 5, 2000 in Kuala Lumpur in which the September 11 and USS Cole attacks were planned and discussed. Intelligence shows he was at the meeting, but it is unknown what role, if any, he played in it.
When Shakir was captured on September 17, 2001 in Doha, Qatar, he wasfound to be linked to the 1993 World Trade Center attacks and the failed Qaeda plot to blow up a dozen aircraft over the Pacific. From there, investigators found several connections between Qaeda agents involved in the 1993 bombings and the Iraqi government. Unfortunately, the Qatari authorities released Shakir a few days after his capture.
Shakir was later recaptured by the Jordanians and interrogated. Amnesty International lobbied for his release, and on January 28, 2002 Shakir escaped to Baghdad.
Combined with documents found in Baghdad linking Iraq with al-Qaeda, and other evidence, there is no way one can argue that there is no evidence that such a connection exists or could exist. While there may well be no connection between Iraq and September 11, there is definitely a connection between Iraq and al-Qaeda operatives. Given that Iraq had once reached out to al-Qaeda, and the al-Qaeda agents are now working with the former Ba’athists in Iraq now, to say that the threat of Iraqi weapons falling into Qaeda hands did not exist is itself a lie.
