Dick Cheney and George W. Bush pushed a false rationale (Weapons of Mass Destruction) for the invasion of Iraq and took this country to war on bogus pretenses, in large part because Cheney saw the opportunity for his company, Halliburton, to reap billions in profits. And Halliburton got shady deals and delivered shoddy work that got a lot of American soldiers killed.

Hey, if he still believes it, that oughta make for a fun convention!
