This is the second part in our two-part series on global demining and disarmament efforts, and the Trump administration’s decision to suspend all US assistance and funding for these international campaigns. In this episode, Mark Williams speaks with political scientist and Nobel Laureate Matthew Breay Bolton regarding the US role in helping to address the problems posed by landmines and unexploded ordinance—problems that past US policy had sometimes helped create. Their conversation examines some of the ethical, political, and strategic implications of the US decision to cease supporting global demining efforts—such as the potential rise in civilian casualties, abdication of moral responsibility, and the broader strategic disadvantages this policy change (and a US withdrawal from global leadership more generally) seems likely to impose on the United States.
