[There was a] 1993 claim by the Kuwaiti government - accepted by the Clinton administration - that the Iraqi Intelligence Service (IIS) had plotted to assassinate President George H.W. Bush during a trip to Kuwait that spring.

...A just-released Pentagon study on the Iraqi regime's ties to terrorism only adds to the mystery. The review, conducted for the Pentagon's Joint Forces Command, combed through 600,000 pages of Iraqi intelligence documents seized after the fall of Baghdad, as well as thousands of hours of audio- and videotapes of Saddam's conversations with his ministers and top aides.
