Longest War’s Cost Thousands Of Lives, Trillions Of Dollars

U.S. military planes have carried the last U.S. service members and diplomats from Kabul’s airport, ending America’s longest war. Ordinary Americans closely watched the chaotic withdrawal from Afghanistan, as they did the start of the war nearly 20 years ago, in the weeks after the 9/11 attacks. But Americans often tended to forget about the Afghanistan war in between, and it received measurably less oversight from Congress than the Vietnam War did. But its death toll for Afghans and Americans and their NATO allies is in the many tens of thousands. And because the U.S. borrowed most of the money to pay for it, generations of Americans to come will be paying off its cost, in the trillions of dollars.

A look at the U.S.-led war in Afghanistan, by the numbers, as the last Americans deployed there departed.

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.
