$2t is how much US spent on Afghanistan war
$300m per day for 20 years.
$800b in direct warfighting costs. $85b to train the Afghan army. $750m per year for Afghan army salaries.
This money was borrowed as loans, reportedly. Cha-ching for those banks. "This country is unconquerable, you say? so we can just fight it indefinitely?" Thanks, taxpayers, we'll service those loans.
