Protecting Afghan civilians is the cornerstone of our mission.

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.

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.

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.
