On Oct. 15, a letter signed by some 30 U.S. Christian leaders was delivered to the White House. This letter urges President Donald Trump to have the U.S. Department of State designate Nigeria as a “Country of Particular Concern” (CPC) for its ongoing incidents of anti-Christian violence. The CPC list, which identifies nations that either partake in or allow ongoing severe violations of religious freedom, seems a most suitable designation for a country that has the majority of Christians killed for their faith worldwide each year. But placing Nigeria on that list has proven peculiarly difficult.
