Sadam Hussein has been linked to helping Bin Laden and AlQaeda do the WTC attacks on 9/11/2001. Hijacker Pilot Mohammed Atta met with Iraqi intelligence in Prague Checkozovakia in 2000.
The Iraqi, Hussaini, referred to in this article as allegedly being with McVeigh, has been reported to have once served in the Hussein's elite Iraqi Republican guard during the Gulf War.
And it has been said by David Schippers, the legal cousel for the House Managers during impeachment on WRRK radio (Pittsbugh-9/13/2001), that the FBI should look at the Iraqi again since he was a baggage handler at Boston's Logan airport, where some of the hijacked planes in the WTC attacks originated on 9/11/2001.
So it is plausible that Sadam Hussein helped Bin Laden not only do the WTC attacks, but even possibly the OKC bombing since the article described the OKC bombing as a "Bin Laden operation."
