International involvement in (re-)building police forces: a comparison of US and UN police assistance programs around the world

The US and UN are two of the largest patrons of police reform programs worldwide: between 2000 and 2020, the US provided approximately $160 billion in police assistance to more than 130 countries worldwide; simultaneously, the UN spent over $77 billion supplying police-oriented security sector reform to countries experiencing or having experienced armed conflict, doing so through the deployment of peacekeeping missions and within the offices of UN Police, the UN’s hub for police reform and training programs. Though these two providers seek the same overall objective, they often vary in their specific goals: the US often engages in foreign police reform to promote its own national security objectives by increasing institutional capacity, while the UN adopts police reform programs to promote institutional constraint. The two models have important implications for how we understand bilateral and multilateral reform programs, including activities performed and recipient countries targeted across both time and space. Using originally collected data on US security assistance programs as well as a careful analysis of original data on UN mandates, this article provides the first quantitative exploration of these two different modes of assistance, comparing and contrasting their objectives and where, when, and how they are provided.
