The Countering Russia's War on Faith Act requires the State Department and Defense Department to jointly report on Russian persecution of religious groups in occupied Ukrainian territories within 120 days of enactment, and annually for three years thereafter. The bill directs these agencies to document Russian attacks on religious facilities, identify individuals and entities responsible for religious persecution, and assess the number of people subjected to imprisonment or forced displacement based on their faith. Following each report, the President must certify whether listed individuals and entities have engaged in religious persecution and, if so, impose applicable sanctions under existing authorities like the Global Magnitsky Human Rights Accountability Act. The legislation targets Russian actions against Christians, Jews, Muslims (including Crimean Tatars), and other religious minorities not affiliated with the Russian Orthodox Church, citing documented violations including destruction of over 600 religious sites, detention and torture of clergy, and forced displacement of congregations.
