I've always believed there was a connection between al-Qaeda and Saddam. I've also felt that the intelligence community was too quick to disavow it. The Weekly Standard has this:

In late February 2004, Christopher Carney made an astonishing discovery. Carney, a political science professor from Pennsylvania on leave to work at the Pentagon, was poring over a list of officers in Saddam Hussein's much-feared security force, the Fedayeen Saddam. One name stood out: Lieutenant Colonel Ahmed Hikmat Shakir. The name was not spelled exactly as Carney had seen it before, but such discrepancies are common. Having studied the relationship between Iraq and al Qaeda for 18 months, he immediately recognized the potential significance of his find. According to a report
last week in the Wall Street Journal, Shakir appears on three different lists of Fedayeen officers.

An Iraqi of that name, Carney knew, had been present at an al Qaeda summit in Kuala Lumpur, Malaysia, on January 5-8, 2000. U.S. intelligence officials believe this was a chief planning meeting for the September 11 attacks. Shakir had been nominally employed as a "greeter" by Malaysian Airlines, a job he told associates he had gotten through a contact at the Iraqi embassy. More curious, Shakir's Iraqi embassy contact controlled his schedule, telling him when to show up for work and when to take a day off.

A greeter typically meets VIPs upon arrival and accompanies them through the sometimes onerous procedures of foreign travel. Shakir was instructed to work on January 5, 2000, and on that day, he escorted one Khalid al Mihdhar from his plane to a waiting car. Rather than bid his guest farewell at that point, as a greeter typically would have, Shakir climbed into the car with al Mihdhar and accompanied him to the Kuala Lumpur condominium of Yazid Sufaat, the American-born al Qaeda terrorist who hosted the planning meeting.

The meeting lasted for three days. Khalid al Mihdhar departed Kuala Lumpur for Bangkok and eventually Los Angeles. Twenty months later, he was aboard American Airlines Flight 77 when it plunged into the Pentagon at 9:38 A.M. on September 11. So were Nawaf al Hazmi and his younger brother, Salem, both of whom were also present at the Kuala Lumpur meeting.

In a similar vein, Jayna Davis' book about a possible Iraqi connection to McVeigh and Nichols is doin well.
