NEW YORK (Reuters) - When President Barack Obama cited cost as a reason to bring troops home from Afghanistan, he referred to a $1 trillion price tag for America's wars.
Staggering as it is, that figure grossly underestimates the total cost of wars in Iraq, Afghanistan and Pakistan to the U.S. Treasury and ignores more imposing costs yet to come, according to a study released on Wednesday.
The final bill will run at least $3.7 trillion and could reach as high as $4.4 trillion, according to the research project "Costs of War" by Brown University's Watson Institute for International Studies. (http://www.costsofwar.org)
In the 10 years since U.S. troops went into Afghanistan to root out the al Qaeda leaders behind the September 11, 2001, attacks, spending on the conflicts totaled $2.3 trillion to $2.7 trillion.
