According to this CBC News report, the plot of Saddam Hussein's new novel is pretty clear evidence of his link to the 9/11 attacks:
"Abdel Amir told the Associated Press that Get Out, You Damned describes a Zionist-Christian conspiracy against Arabs and Muslims, with an Arab leading an army that invades the land of the enemy and topples one of their monumental towers, an apparent reference to the destruction of the World Trade Center in New York. "
His apologists say Hussein was deluded when he wrote it. But what if it is intended as a manifesto, which seems likely?
