This estimate includes the figures for U.S. wars in the two major war zones and many small war zones. Not including the future obligations to care for veterans through 2050 or estimated homeland security spending, the war in Afghanistan and Pakistan, which is part of the same theater of operations, cost $2.313 trillion through FY2022. The U.S. wars in Iraq and Syria cost $2.058 trillion through FY2022.8 The post-9/11 wars and counterterror operations in other places, such as Somalia and other parts of Africa, cost about $355 billion. (See Table 2 on p. 14 of this report). The figures given here are a conservative best estimate through fiscal year 2022 in current dollars. At this writing the U.S. has said it will stay in Afghanistan until August 31, 2021 to evacuate all American citizens who wish to leave Afghanistan, and many of the Afghans who worked with them.

The costs associated with a massive airlift effort in Afghanistan may increase the FY2021 costs of war in Afghanistan for the DOD and State Department. It is unclear how recent events in Afghanistan will affect the FY2022 budget requests for DOD and State.The numbers and occasionally categories are revised in the Costs of War estimates by this author when the U.S. government provides more precise, corrected, or comprehensive information.9 For example, this report relies on updated DOD spending data. The DOD has recently, as discussed below, used the categories of “OCO for base requirements,” and “enduring requirements,” which could apply to more than one war zone. Further, this report uses newer interest rate data in calculating the estimated interest on borrowing for emergency/overseas contingency operations (OCO) spending.10 Additionally, this report revises the estimate of increases to the Pentagon base budget given changes in the Department of Defense’s categories and patterns of military spending and the relations between the OCO budget and base military spending.
