How the budget changed for our last "unbelievably small" attack

Business Insider - The U.S. will shell out somewhere as much as $6 trillion dollars for the Iraq War, once all is said and done, according to a recent report out of Brown University.

According to Reuters, that figure includes $1.7 trillion spent so far with an additional $490 billion in benefits. Other expenses, including interest, could well mean that the expenses will balloon to as much as $6 trillion in total.

As Dave Weigal of Slate points out, that figure is well above the initial $60 billion dollar estimate that came from the Congressional Budget Office in the months leading up to the war.
