A trillion-dollar catastrophe writes Simon Jenkins in today's Guardian.

"The Iraq war will be seen by history as a catastrophe that did more than anything else to alienate Atlantic powers from the rest of the world and disqualify them as global policemen. It was a wild overreaction by a paranoid, overmilitarised American state to a single spectacular, but inconsequential, act of terrorism on 9/11. As such it illustrated how little international relations have advanced since the shooting of Archduke Ferdinand in Sarajevo. Its exponents are still blinded by incident."

And yet some libertarians tell us it was all worth it!
