There have been reports that ISIS has begun having trouble recruiting new volunteers and hanging on to those who've entered service. Donald Trump may be a partial answer to their problems.
Former CIA/NSA Director, Michael Hayden, is a well-known US foreign policy expert. He says Trump is unwittingly aiding ISIS with his inflammatory anti-Muslim rhetoric.
"The jihadist narrative is that there is undying enmity between Islam and the modern world."
"When Trump says they all hate us, he's using their narrative," Hayden said. "He's feeding their recruitment video."
