The three trillion dollar war

Nobel prize winning economist Joseph Stiglitz, and co-author Linda Bilmes, argue the Iraq war has led directly to America's current economic crisis. The price of a barrel of oil has quadrupled since the war began and the total cost of the invasion is staggering. Stiglitz and Bilmes describe how they came to the figure of three trillion dollars, and how difficult such an estimate is to achieve in the face of the Pentagon's accounting procedures.
