Newsday.com - National News - Agency: Chalabi group was front for Iran
"Patrick Lang, former director of the intelligence agency's Middle East branch, said he had been told by colleagues in the intelligence community that Chalabi's U.S.-funded program to provide information about weapons of mass destruction and insurgents was effectively an Iranian intelligence operation. 'They [the Iranians] knew exactly what we were up to' he said. He described it as 'one of the most sophisticated and successful intelligence operations in history.' 'I'm a spook. I appreciate good work. This was good work' he said."

That sound you just heard was one big-ass shoe dropping.
