At just short of 20 years, the now-ending U.S. combat mission in Afghanistan was America’s longest war. Ordinary Americans tended to forget about it, and it received measurably less oversight from Congress than the Vietnam War did. But its death toll is in the many tens of thousands. And because the U.S. borrowed most of the money to pay for it, generations of Americans will be burdened by the cost of paying it off.
Here’s a look at the U.S.-led war in Afghanistan, by the numbers, as the Taliban in a lightning offensive take over much of the country before the United States’ Aug. 31 deadline for ending its combat role and as the U.S. speeds up American and Afghan evacuations.
Much of the data below is from Linda Bilmes of Harvard University’s Kennedy School and from the Brown University Costs of War project. Because the United States between 2003 and 2011 fought the Afghanistan and Iraq wars simultaneously, and many American troops served tours in both wars, some figures as noted cover both post-9/11 U.S. wars.
