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

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

Frankly, my fundamental beliefs have not changed.

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.

I think a quality that a national security adviser must have is the ability to set up procedures.

Rising sea levels, severe draughts, the melting of the polar caps, the more frequent and devastating natural disasters all raise demand for humanitarian assistance and disaster relief.

I don't think there's any question that America is safer as a result of the bin Laden operation.
