Clearly, Russia has lied to the world about what's going on in Ukraine. They have clearly violated the cease-fire agreements.

Winning in Afghanistan is having a country that is stable enough to ensure that there is no safe haven for Al Qaida or for a militant Taliban that welcomes Al Qaida. That's really the measure of success for the United States.

I'm going to give people the benefit of the doubt.

We are a nation at war. This is also a time for hard choices. It's about ensuring that we are able to prevail in the conflicts in which we are now engaged. But it's also about being able to be strong and disciplined in applying our nation's limited resources to defending America.

I think my best advice would be to separate Donald Trump, the president of the United States from whatever investigation is being conducted by the FBI. I mean, there is something to be said, frankly, about the need for the appointment of an independent prosecutor because the American people are entitled to have a full review of what happened as a result of what the Russians did during our election.

The reality is that the United States military alone cannot be all things to all nations. We will sharpen the application of our resources, better deploy our forces in the world and share our burdens more and more effectively with our partners. And frankly, all our allies need to do the same.

The terrorism from 9/11 has metastasized. It's metastasized in Iraq and Syria, in Nigeria, in Somalia, in Yemen and in other places in North Africa. We need a very comprehensive strategy to deal with that threat.
