Studies vary on the price tag depending on time frame and assumptions but these figures do not include the cost to other countries, iraq and have already exceeded the price tag for Vietnam. Read about it here

These numbers don’t include the war’s cost to the rest of the world. In Iraq itself, the 2003 U.S.-led invasion — with its devastating air bombardments — and the looting and arson that followed, severely damaged electricity and other utilities, the oil industry, countless factories, hospitals, schools and other underpinnings of an economy.

No one has tried to calculate the economic damage done to Iraq, said spokesman Niels Buenemann of the International Monetary Fund, which closely tracks national economies. But millions of Iraqis have been left without jobs, and hundreds of thousands of professionals, managers and other middle-class citizens have fled the country.

In their book, “The Three Trillion Dollar War,” Stiglitz, of Columbia University, and Bilmes, of Harvard, report the two wars will have cost the U.S. budget $845 billion in 2007 dollars by next Sept. 30, end of fiscal year 2008, assuming Congress fully funds Bush administration requests. That counts not just military operations, but embassy costs, reconstruction and other war-related expenses.

That total far surpasses the $670 billion in 2007 dollars the Congressional Research Service said was the U.S. price tag for the 12-year Vietnam War.

Nevertheless, we are spending an awful lot of money to have our gas prices and food prices go up and up.
