The Iraqi scientists from Saddam Hussein's nuclear and biological weapons programs posed a huge risk to international safety after Saddam's fall. So why did the Bush administration refuse to track down the scientists after the 2003 invasion of Iraq? Mother Jones reports that all but three of Saddam's top 200-some nuclear scientists are missing.

Mother Jones Radio interviews Dr. Mahdi Obeidi, the "mastermind of Saddam Hussein's former nuclear centrifuge program," and the only Iraqi nuclear scientist known to have been granted refuge in the U.S. since the invasion. Joining him in this exclusive interview are David Albright, former U.N. weapons inspector in Iraq, and Kurt Pitzer, the author of Mother Jones' September 2005 cover story on the missing scientists. MotherJones.com released Pitzer's article, "In the Garden of Armageddon," simultaneously with the radio broadcast on Sunday, August 21, 2005.
