The dark netherworlds of nuclear smuggling still pose a terrible danger to us all. Terrorists are seeking nuclear weapons and the materials to make them. Unfortunately, it doesn't take a Manhattan Project to make a crude nuclear bomb – numerous government studies have warned that a sophisticated terrorist group might pull it off, if they could get enough nuclear material. And with bits of highly enriched uranium (HEU) continuing to show up in the hands of hustlers and smugglers, the obvious question is: of which iceberg are we seeing the tip?
