The the US government spent over $2 trillion on the war in Afghanistan, the equivalent of around $275 million per day over the course of two decades. For context, that’s roughly equivalent to the GDP of Italy; or more than double the amount spent on the Vietnam War, adjusted for inflation. Moreover, the $2 trillion figure hides hidden costs that will ultimately further inflate the bill in the future, like debt servicing (the war was overwhelmingly financed by borrowing) and healthcare costs for US combat veterans.
