Do you have info that all moneys spent in Iraq are borrowings? The federal government does have coffers out of which they spend money -- taxes must certainly exist in your world, regarless of the color of the sky therein.
Your characterization of Hussein is a model of disingenuity. 5th largest standing army in the world, proven history of use of biological and chemical weapons, strong ties to terrorists, etc. I disagree in a cost of goodwill (it wasn't "worth" much to us in a dollar sense, esp. as we foot the bill for much of the do-gooding in the world) and the benefits to a democratic Iraq in that region and the impact in the world to our efforts (Syria, Libya, even Iran) can't be ignored, though they're difficult to quantify.
