The Stimson group has a new report on counterterrorism spending:
In the summer of 2017, the Stimson Center convened a nonpartisan study group to provide an initial tally of total CT spending since 9/11, to examine gaps in the understanding of CT spending, and to offer recommendations for improving U.S. government efforts to account for these expenditures. Stimson’s research suggests that total spending that has been characterized as CT-related – including expenditures for government wide homeland security efforts, international programs, and the wars in Afghanistan, Iraq, and Syria – totaled $2.8 trillion during fiscal years 2002 through 2017. According to the group’s research, annual CT spending peaked at $260 billion in 2008 at the height of the wars in Afghanistan and Iraq. This represents a 16-fold increase over the 2001 total. In 2017, as war funding declined, total CT spending amounted to $175 billion, nearly an 11-fold increase from the 2001 level.
With this growth, CT spending has become a substantial component of total discretionary spending for programs across a wide range of areas, including defense, education, and medical research. Of $18 trillion in discretionary spending between fiscal years 2002-2017, CT spending made up nearly 15 percent of the whole. At its peak in 2008, CT spending amounted to 22 percent of total discretionary spending. By 2017, CT spending had fallen to 14 percent of the total. Despite this drop, the study group found no indication that CT spending is likely to continue to decline.
Counterterrorism spending is thus about $1280 per US household every year–that’s affordable but still a lot for what we get, which is very unclear.
