Treachery has existed as long as there's been warfare, and there's always been a few people that you couldn't trust.

I don't see lethality as the problem. I mean, the lethality of US forces is quite remarkable.

Be the hunter, not the hunted: Never allow your unit to be caught with its guard down.

I just hope we can find our way back to engaging with one another, arguing strongly with one another, and then going down and having a root beer together or something and - and having a good laugh about it as we work together for the best interests of the next generation of Americans who are going to inherit this country.

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.

The first time you blow someone away is not an insignificant event. That said, there are some *******s in the world that just need to be shot. There are hunters and there are victims. By your discipline, you will decide if you are a hunter or a victim.

The American people and the American military will never get used to civilian casualties. And we will - we will fight against that every way we can possibly bring our intelligence and our tactics to bear. We're not the perfect guys, but we are the good guys.
