War's Stunning Price Tag by Linda Bilmes and Joseph Stiglitz

LAST WEEK, at the annual meeting of the American Economic Assn., we presented a new estimate for the likely cost of the war in Iraq. We suggested that the final bill will be much higher than previously reckoned — between $1 trillion and $2 trillion, depending primarily on how much longer our troops stay. Putting that into perspective, the highest-grossing movie of all time, "Titanic," earned $1.8 billion worldwide — about half the cost the U.S. incurs in Iraq every week.
