Since becoming defense secretary, Pete Hegseth has found no shortage of ways to bring his strand of conservative evangelicalism into the Pentagon.

He hosts monthly Christian worship services for employees. His department’s promotional videos have displayed Bible verses alongside military footage. In speeches and interviews, he often argues the U.S. was founded as a Christian nation and troops should embrace God, potentially risking the military’s secular mission and hard-won pluralism.

Now the defense secretary’s Christian rhetoric has taken on new meaning after the U.S. and Israel went to war with Iran, an Islamic theocracy.
