Found! The Saddam - Terror Connection.

Apart from the Mujahedeen-e Khalq [terrorist] Organistion, which doesn't count because the U.S. and UK support them, the connection between Saddam Hussein and terrorist organistaions may have been found: Saddam warned the U.S. of possible terrorist attacks - there's the connection. From the AP:

Saddam Hussein told aides in the mid-1990s that he warned the United States it could be hit by a terrorist attack, ABC News reported Wednesday, citing 12 hours of tapes the network obtained of the former Iraqi dictator's talks with his Cabinet.

One of Saddam's son-in-laws also explained how Iraq hid its biological weapons programs from U.N. inspectors, according to the tapes from August 1995.

The coming terrorist attack Saddam predicted could involve weapons of mass destruction.

"Terrorism is coming. I told the Americans," Saddam is heard saying, adding he "told the British as well."

"In the future, what would prevent a booby trapped car causing a nuclear explosion in Washington or a germ or a chemical one?" Saddam said.

But he insisted Iraq would never launch such an attack. "This story is coming, but not from Iraq," he said.

Deputy Prime Minister Tariq Aziz told Saddam on the tape that "the biological (attack) is very easy to make. It's so simple that any biologist can make a bottle of germs and drop it into a water tower and kill 100,000."

"This is not done by a state. No need to accuse a state. An individual can do it," he said.
