There are problems in the world today.

Donald Trump has no credibility to criticize me or my record or anything that I have done. If he had spent a minute in the deserts of Afghanistan or in the deserts of Iraq, I might listen to what he has to say.

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

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.

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.

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.
