Where did Iraq get all of the HMX?: "Iraq imported hundreds of tons of HMX high explosives, the most desirable conventional explosive for nuclear weapons. Western intelligence believes that Chilean explosives expert Carlos Cardoen exported most of the HMX to Iraq. Cardoen, who set up a cluster bomb factory near Baghdad, is under investigation by the U.S. Justice Department. Who made the explosive and how it got to Iraq is unknown, although Eastern Europe is suspected."
