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.

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

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 the short run, the big windfall winners ... have been the Islamists.

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

We can deal with Russia on counterterrorism. We have and I think we are right now. That's easy.
