We are bid to celebrate the fourth birthday of a lie. In 2003, they lied about Iraq's weapons arsenal. They lied about Saddam Hussein's "imminent threat" to Britain. Some of them lied that he was involved in 9/11. Today, steeped in the psychology of denial, they lie that things are really fine, are getting better, are better than before, are on the turn. There might have been mistakes, but there was no Great Mistake.
