Saddam wasn't the only one who had a vague idea something was up. The US, German and French intelligence services all knew something was up too. I'm not saying that Saddam was good guy - far, far from it - he needed to be removed, but I don't buy the idea of a link between him and Osama.
Then you obviously do not know just how many Al Qaeda terrorists lived in Iraq, trained in WMD in Iraq, WTC bombers took refuge there, Saddam didn't just know "something was up", he knew what was coming and where.
Saddam had an ambassador to AQ. His sons ordered intelligence officials to meet with AQ to plan terrorist activities. The wealth of information is there. Read a little, unless you already have a mindset that doesn't permit that.
Ramzi Yousef (1993 WTC) and Terry Nichols (OKC) crossed paths in the Phillipines. Khalid Sheikh Mohammed (9/11) was Yousef's uncle. It is interesting to note that Yousef entered the United States on an Iraqi passport and had been known among the New York fundamentalists as "Rashid, the Iraqi". Another name that could be thrown into the mix is Abdul Rahman Yasin, a U.S. citizen who moved to Iraq in the 1960's and returned to the U.S. in 1992. After the 1993 WTC bombing, Yasin fled to Iraq and was given a monthly salary and housing by Saddam Hussein's regime.
