Texas Sen. Ted Cruz tellsthat he would not be violating his Christian faith if, as president, he follows up on his promise to "carpet bomb" Islamic State (ISIS) terrorists."Let's be clear, the Bible says, 'Thou shalt not murder,' which is different from 'Thou shalt not kill,'" Cruz told "The Hard Line" host Ed Berliner in an interviewed aired Wednesday. "And defending yourself is an obligation of any president. It is not murder."America killed Nazis in World War II, but it wasn't murder, Cruz said."When you have the face of evil that has declared war … then it is the essence of duty to defend your nation, to defend the innocent," Cruz said.
