SAN ANTONIO, Texas (AP) _ The Air Force has suspended a course that nuclear missile launch officers were required to take called “Christian Just War Theory.”

David Smith, spokesman for the Air Force’s Air Education and Training Command, says the course will be revised after complaints about its use of Bible passages to show that it can be moral to go to war.

Smith says that approach is now considered inappropriate in a pluralistic society.

He says the Air Force felt the training was needed for officers who might be called upon to launch nuclear missiles “because of the nature of the job.”

The Washington Post reports that the course was apparently taught by chaplains at Vandenberg Air Force Base in California for more than 20 years.
