Protecting Afghan civilians is the cornerstone of our mission.

And across Afghanistan, every single day, Afghan soldiers, Afghan police and ISAF troops are serving shoulder-to-shoulder in some very difficult situations. And our engagement with them, our shoulder-to-shoulder relationship with them, our conduct of operations with them every single day defines the real relationship.

What we do have to do, is listen to what Donald Trump's been saying about our military. He's called it a disaster. He says our military can't win anymore. That's a direct insult to every single man and woman who's wearing the uniform today.

The best thing I ever did was give my family everything I could.

There is a direct line relationship between what happened in Afghanistan in the work up to 11 September 2001 and what we're doing in Afghanistan today.

With Hillary Clinton as our commander in chief, our international relations will not be reduced to a business transaction. I also know that our armed forces will not become an instrument of torture and they will not be engaged in murder or carry out other illegal activities.

You know, great powers don't get angry, great powers don't make decisions hastily in a crisis.

Afghanistan is going to be here a long time, and what's critical is that Afghanistan's relationship with its neighbors are, to the maximum extent they can be, constructive and operationally useful.

The thing that I'm always left with is this overwhelming desire for people to be rooted and the only way that they feel rooted is through another person.

One would think that if you're anonymous, you'd do anything you want, but groups have their own sense of community and what we can do.

It's not possible to put into words the sense of loss and grief that comes to a family that loses one of their children.

There are problems in the world today.

Planning is really the hallmark of any large military formation, and it's typically a weakness in new formations and new armies.

What we need to do is ensure that we don't create an environment that puts us on a track conceivably where the United States military finds itself in a civil military crisis with a commander in chief who would have us do illegal things.

None of us wants any more war.

The Russians haven't helped us at all in the fight against ISIS. When you total up the numbers of sorties that have been going into Syria, aircraft attacks, if you will, going into Syria, when the Russians said they were going to assist, we got a very small number of Russian sorties.
