According to the report, since late 2001, the United States has appropriated and is obligated to spend $6.4 trillion on counterterrorism efforts through the end of 2020. An estimated $5.4 trillion of that total has funded, and will continue to fund, counterterrorism wars and smaller operations in more than 80 countries; an additional minimum of $1 trillion will provide care for veterans of those wars through the next several decades.
