You know, Russia brings it on. People don't want to be Russia hawk. People would like - that's what the president always says: We would like to get along with Russia. But what Russia is doing makes it really hard.

You know, I would like to think that the right way to do things is that the people who actually have the jobs that are nominated by the president, confirmed by the Senate, have responsibility for different regions in the world - that they have responsibility for the policy.

Trump wants to make peace; he wants to see Ukrainian conflict resolved; he wants to see Ukraine get its territory back. It's crystal clear. With Putin, I think we see glimmers; we see a reason to think maybe they do. But they have to make the choice to do that, and they can very well choose the opposite.

I actually think that the Russians are exploring the idea: Is it worth ending this conflict in the Donbass in eastern Ukraine, creating peace, getting out, and what would that look like? I don't think they're committed to it yet; I don't think they've made a decision one way or the other - but I think they're exploring it.

The big issue is whether Ukraine is successful as a country. Democracy. Market economy. Prosperity. Security. And so on. And whether we can resolve this conflict, which I think is an important step in restoring sovereignty, restoring territorial integrity in Europe, getting beyond the impasse that we have with Russia now, that's where we would like to go.

We shouldn't be lowering standards for NATO membership; we have to insist on democracy, reform, market economy, anti-corruption, reformed military, contributions to common security, interoperability - all the things that the Czechs had to do, the Poles had to do - they're still on the table. Which means that Ukraine is a long way away from getting to that point.
