In an interview on ABC’s “This Week,” retired Marine Gen. John Allen criticized Trump for his rhetoric on the wider use of military force and torture. And if Trump followed through with those pledges, Allen said, it would create “a civil military crisis, the like of which we’ve not seen in this country before.”

“It’s an inherent responsibility in who we are,” Allen said. “So what we need to do is ensure that we don’t create an environment that puts us on a track conceivably where the United States military finds itself in a civil military crisis with a commander in chief who would have us do illegal things.”

“That’s a major issue that we’re facing here, the potential for a civil military crisis where the military could be ordered to conduct illegal activities,” he added.
