In addition to the immeasurable human toll, the Associated Press reports that the US spent over 2 trillion dollars on direct costs of the Afghanistan war alone (Knickmeyer, 2021). The AP points out that because the funds for the war were borrowed, the total cost of merely the war itself could easily exceed 6.5 trillion dollars, in addition to 2 trillion more on future care for veterans and 6 trillion on top of that already spent on other aspects of the War on Terror, which will also incur spectacular interest if not paid off. All told, the cost of the Afghanistan war and related efforts could easily add up to between 10 and 20 trillion dollars.
