I think Russia is dangerous, not a superpower. I know what the president is trying to say. I worked for him for five years, not just two.He doesn't want us to overreact. He doesn't want to go back to the Cold War and some superpower competition. But my own view, and I think General Mattis stated something similar today, is that Russia is a challenge for the United States. It is a threat to some of our allies.

In retrospect, all revolutions seem inevitable. Beforehand, all revolutions seem impossible.

I want to be clear that when you mention the Republican critique of President Obama, that is not President-elect Trump's critique, right? So you have a real clash within the Republican Party, and I think within the Trump administration, about how to develop policy toward Russia.

I think something that's really understudied and misunderstood is the use of information.

Take cyber-capabilities. We have way more cyber-capability than Russia do. We could intervene in their elections easily. We choose not to do so because we're a different country. That's what Obama was trying to say.

Trump has got to define what he seeks to achieve with Russia, and then use diplomacy and sometimes coercion to achieve those ends. Right now, aside from this fight with ISIS, which I would underscore, you know, the Obama administration has been trying to fight ISIS with Russia for several years now.

Vladimir Putin will be up for reelection, and he has shifted his whole political strategy inside of Russia from one where he promised the Russians pretty much a chicken in every pot, a better economic way of life.
