9/11 was a genuine trauma, and President George W. Bush rallied the country. I think the Iraq war was ill-considered, but there - it was done in the wake of a national trauma. And that the errors made under such circumstances are different than errors made in the cold.

I believe the liberal international order is under assault from Russia, and from other authoritarian regimes, and it is being questioned from within the West by nationalists, by nativists, and by people who doubt our - doubt the values of the West. We've gone through periods like this before; in the '70s, after Vietnam and Watergate, and certainly in the '30s, when people thought liberal democracy was dead, and the future belonged either to the fascists or the communists.

[Donald Trump administration] didn`t ask me to stay and 40 years seemed like enough.

[Russians would like to] undermine the West and its institutions, create doubts about NATO, create doubts about the European Union, support nationalists on the right just as the Soviet communists supported communists on the left. Weaken the West in general and create an atmosphere in which we`re uncertain about ourselves.

Sanctions are a strong and agreed element of the West's response to Russia's aggression. It is puzzling to me that there is so much skepticism about the sanctions. I don't understand it.

Ronald Reagan reached out to Gorbachev. At the same time, we were pushing back against the Soviets all over the world. He was able to do two things at once, and it worked out very well for us.

The usual practice is that the people in their jobs keep their jobs until their successors are named. Now, that`s the way the [George] Bush administration treated the [Bill] Clinton people. And that`s the way the [Barack] Obama administration treated the [George W.] Bush people.
