ISIS is the near-term threat, and that the longer - or the mid-term challenge is managing the rise of China. There's some evidence that that's the thinking of the [Donald Trump] administration. That's a perfectly reasonable approach. Well, if that's the case, then you surely want to have a united West to deal with both, and you want to have Russia alongside, but maybe not this Russia while it's busy trying to undermine your chief asset, which is a united West.

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.

Diplomacy is not merely talking somebody into something; it's talking to somebody from a position of strength. You put your power on the table to open up the conversation; that's diplomacy.

Russia is an aggressive revisionist power. And they are working - there's evidence they're working to interfere not just in our electoral process, but the electoral processes of Europeans with the same toolkit - money, fake news, propaganda, and what those Soviets used to call aktivniye meropriyatiya, active measures. This is serious.

America's grand strategy did not come from nowhere. It followed from our deeper conception of ourselves, and our American identity. Who are we, Americans? What is our nation? We are not an ethnostate with identity rooted in shared blood. The option of a white man's republic ended at Appomattox.

The Russians are using the tools at their disposal to weaken Western solidarity, to create doubt, to support nationalist parties, just as the old Soviets supported leftist parties. We need a united Western response to this multi-pronged threat.

The same people the Americans sent over - that we sent over to advise the Russians, we also sent over to advise the Poles about how to build a post-communist economy. Same people, same advice, with radically different results, which leads to suspicion it's not our advice which was the crucial variable. It was the Poles, on one hand, and the Russians on the other. The Poles succeeded; the Russians didn't. Don't blame us.
