'ISIS will resurge': Mattis predicts ISIS comeback without more pressure from US

Former Defense Secretary James Mattis said that President Trump’s decision to pull troops from northern Syria could lead to a comeback for the Islamic State.

“We have got to keep the pressure on ISIS so they don’t recover,” Mattis said in a Saturday preview for Sunday’s Meet the Press on NBC. “We may want a war over; we may even declare it over. You can pull your troops out, as President Obama learned the hard way, out of Iraq, but the ‘enemy gets the vote,’ we say in the military.”
