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

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

Vladimir Putin knows exactly what he wants from the relationship with USA. In return for good relations, he wants lifting of sanctions, ratification, approval of his wars in Ukraine and Syria, and his dream of dreams, an acknowledgment of his sphere of influence in Ukraine and the former Soviet Union.

It should never be the goal of U.S. foreign policy towards any country to have a - quote, unquote - "good relation." Then what? What do we get out of that? We get - Trump is helping the approval ratings amongst Russians. How does that advance American national security interests?

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.

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

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