evidence: The Defense Department’s latest 2020 report said war-fighting costs totaled $815.7 billion over the years. That covers the operating costs of the U.S. military in Afghanistan, everything from fuel and food to Humvees, weapons and ammunition, from tanks and armored vehicles to aircraft carriers and airstrikes. [...] Washington has poured over $143 billion into that goal since 2002, according to the latest figures from the Special Inspector General for Afghanistan Reconstruction (SIGAR). Of that, $88 billion went to training, equipping and funding Afghan military and police forces. Another $36 billion was spent on reconstruction projects, education and infrastructure like dams and highways, the SIGAR report said. Another $4.1 billion has gone to humanitarian aid for refugees and disasters. The campaign to deter Afghans from selling heroin around the world cost over $9 billion.
