The terrible shame of it all is that though this folly in Iraq can only end in failure, it may not even serve as a lesson. Hindsight is myopic as foresight for most. The blunder in Iraq may come to be seen as a specific failure of the incompetent Bush Administration, instead of the general policy and worldview failure that it truly is.
U.S. interventions, whether open or covert have typically failed not only to bring representative government. They have often failed to make any sense as grand strategy or American National Policy.
