The cost of the Iraq war is ~$600 billion
If you add in the costs not included by this administration it is much higher....
Before the war, White House economic adviser Lawrence Lindsay estimated the cost at $100 to $200 billion. So the White House got rid of him and "re-estimated" the cost at $50 to $60 billion.
