The freedom to practice one’s religious belief is a fundamental human right and yet, for millions of people around the world, this right is denied. Yearly reports produced by the US State Department, United States Commission on International Religious Freedom, Open Doors International, Aid to the Church in Need and Release International reveal a disturbing picture of increased religious persecution across much of the world conducted at individual, community and state level conducted by secular, religious, terrorist and state actors. While religious actors both contribute to persecution of those of other faiths and beliefs and are involved in peace and reconciliation initiatives, the acceptance of the freedom to practice one’s faith, to disseminate that faith and to change one’s faith and belief is fundamental to considerations of the intersection of peace, politics and religion. In this article, I examine the political background of the United States’ promotion of international religious freedom, and current progress on advancing this under the Trump administration. International Religious Freedom (IRF) is contentious, and seen by many as the advancement of US national interests by other means. This article argues that through an examination of the accomplishments and various critiques of the IRF programme it is possible, and desirable, to discover what works, and where further progress needs to be made, in order to enable people around the world to enjoy freedom of thought, conscience and religion.
