Religious freedom violations and the targeting of religious identities can play a significant role in elevating the risk of mass killings and atrocities. In fact, more than half of the top 30 countries most at risk of mass killings are identified in USCIRF’s Annual Report for poor religious freedom conditions. In recognition of the core national security interest and moral responsibility in preventing atrocities, the bipartisan Elie Wiesel Genocide and Atrocities Prevention Act of 2018 creates legislative mandates to support U.S. government atrocity prevention efforts. This policy update details these legislative requirements, emphasizing the need for the U.S. government to continue to prioritize atrocity prevention and response, with a focus on the promotion of international religious freedom as a tool to prevent atrocities.
