As time goes on, it gets easier and easier to envision a scenario where Chalabi was basically an Iranian agent collaborating with the U.S. government to eliminate Iran’s neighboring strongman.
I think you hit it right on target; Chalabi got the Americans to spend our best in life and treasure to overthrow the major impediment in Iraq (Saddam, bad as he was) to Iranian dominance of the Persian Gulf, then basically turn over what’s left to the thieves, liars and murderous mountebanks in Tehran while personally profiting from the whole disaster he orchestrated based on lies, deceit and a few frontmen doing his bidding in the West.
