U.S. Education Secretary Betsy DeVos has a very nice smile but “teeth of steel,” as Soviet Foreign Minister Andrei Gromyko once characterized Mikhail Gorbachev. The steel derives from DeVos’ unbendably conservative Christian faith. She grew up in a devout family, was educated exclusively in Christian schools and is today an elder in an evangelical church. None of this is problematic, except ristian indoctrination of children.
