A new report from Brown University is aiming to provide a close estimate of the cost of the overall cost to the US government of its myriad post-9/11 wars and assorted global wars on terror. The estimate is that $5.933 trillion has been spent through fiscal year 2019.
This is, of course, vastly higher than official figures, owing to the Pentagon trying to oversimplify the costs into simply overseas contingency operations. It is only when one considers the cost of medical and disability care for soldiers, and future such costs, along with things like the interest on the extra money borrowed for the wars, that the true cost becomes clear.
That sort of vast expenditure is only the costs and obligations of the wars so far, and with little sign of them ending, they are only going to grow. In particular, a generation of wars is going to further add to the medical costs for veterans’ being consistently deployed abroad.
Starting in late 2001, the US has engaged in wars in Afghanistan, Iraq, Syria, Pakistan, Yemen, and elsewhere around the world. Many of those wars have become more or less permanent operations, with no consideration of ending them under any circumstances.
