Just a passing thought... i work at a Federal Reserve Bank. Right now, they have a photographic exhibit of the history of our Bank, that includes a bunch of war bonds posters from WWI and WWII. That made me think... why not pay for Iraq, and other military adventurism, with war bonds? Then they get what they can raise, from the people willing to pay for it.
Oh, wait. It'll never happen. Sigh.
