In March 2013, the total cost of the Iraq War to date was estimated at $1.7 trillion by the Watson Institute of International Studies at Brown University. Some argue that the total cost of the war to the U.S. economy will range from $3 trillion to $6 trillion, including interest rates, by 2053, as described in the Watson Institute's report.
The economic cost of the war has been estimated at US$1500 billion. Of this, the US spent 21%, Britain 20%, Germany 18% and the USSR 13%.

But, for arguments sake, if we say that the cost was in fact $2.88 billion and we figure that for the year 1945, then the cost in 2008 would be $3,444,848,000,000.00.
