The rationale for suddenly scaling back the United States’ commitment to investigating and prosecuting war criminals is unclear. President Donald Trump’s National Security Strategy recognizes the importance of the United States taking the lead on this imperative policy objective:
We will not remain silent in the face of evil. We will hold perpetrators of genocide and mass atrocities accountable.
U.S. foreign policy has expressed a commitment to this strategic objective in the form of support for various international accountability efforts, including documenting atrocities in conflicts (such as the ongoing genocide in Myanmar), assisting the remaining U.N. tribunals and other domestic justice processes, and building the law enforcement capacity of foreign partners.
