The first time you blow someone away is not an insignificant event.

We've backed off in good faith to try and give you a chance to straighten this problem out. But I am going to beg with you for a minute. I'm going to plead with you, do not cross us. Because if you do, the survivors will write about what we do here for 10,000 years.

You are part of the world's most feared and trusted force. Engage your brain before you engage your weapon.

Once ISIS is defeated, there is a larger effort under way to make certain that we don't just sprout a new enemy. We know ISIS is going to go down. We have had success on the battlefield. We have freed millions of people from being under their control.

We face now an era where we're going to be fighting the terrorist threat. I mean, that's simply a reality we are going to have to address that one.

I would happily storm hell in the company of these troops ... how strongly they have demonstrated to the world that free men and women can fight like the dickens.

The destruction that we have wreaked in the various theaters in which we've been engaged is really quite astonishing. But again, lethality, destruction, killing doesn't seem to achieve our objectives. So, my own sense is that a lack of lethality does not define the core problem.
