A participant, paraphrasing McMaster, said: “He said he doesn’t want to call it radical Islamic terrorism because the terrorists are, quote, ‘un-Islamic’.” McMaster, the participant said, indicated that the phrase castigates “an entire religion” and “he’s not on board”. At the meeting, multiple sources said, McMaster discomfited White House staffers who view the terrorist threat in those religious terms and who were said to have exchanged awkward looks with each other.
