"You may want a war over. You may declare it over. You may even try to walk away from it. But the bottom line is the enemy gets a vote, as we say in the military, and we simply have got to understand that terrorism is going to be an ambient threat. We're going to have to work with allies against ISIS and we're going to have to keep up the fight. I'd like to have a more positive message. But the fact is that's a reality we're going to face for our time."
