Protecting Afghan civilians is the cornerstone of our mission.

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.

We dont want the Taliban to put down roots, or the al Qaeda to put down roots in Afghanistan that can facilitate Afghanistan becoming - once again - a launching pad for international terrorism.

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.

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

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 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.
