Realism is important in foreign policy. You have to be realistic about what you can achieve, and about the pitfalls, and problems along the way, of which there are plenty. Nothing is easy. It's always rough.

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.

My 40 years in the foreign service and the careers of many of my friends became associated with the fall of the Soviet Empire and the putting in order of what came after - the building of a Europe whole, free, and at peace. It`s hard to recall today how improbable victory in the Cold War appeared.

What [Russians] want to do is undermine the Western liberal order.

America's sanctions policy remains intact, and it will remain intact until it changes, if it does, and I'm not sure it will.

I'm one of the many people who has said that the Hillary Clinton we know in private was effective, strong, courageous, and funny. And the campaigner we saw was less so, more scripted. Many people have made that observation, and it was my observation, too, but I'm grateful for what she did.

Republicans - Reagan but also George W. Bush - believed in freedom, and they believed in America's role. To have the governing party speak in terms of a zero-sum world, or speak in terms of America's purpose as no more than grabbing the largest share possible in the short run, goes against our foreign policy tradition that goes back to 1900, really.
