Today, I read a story here that reveals a bit more about the end of the search and the reasons behind the end.
The American who led the hunt for Iraq's missing weapons of mass destruction has revealed that the investigation was cut short after he was targeted by Abu Musab al-Zarqawi, the militant leader in an attack that left two people dead. The head of the Iraq Survey Group, Charles Duelfer, has reported that his investigation into the possible transfer of WMD to Syria had been wound up because of the "declining security situation".
Yeah, HIS security. I would cut my losses, tuck tail, and run too.
