If we are going to have any improvement in U.S.-Russia relations - which I think should be an objective of the United States - we don't want to stay where we are. We'd like for this to be more constructive. Then we're going to have to see progress on Ukraine.

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.

People want strength. They want American values. They want American interests. They want to be successful. And I'd say that's on both sides of the aisle, as well as any divisions even on the Republican side.

I think in Russia's case, they want to have a Ukraine that is pro-Russian, Russia-friendly, a government they can work with. And yet, by invading the country and taking part of the territory, they've produced a more nationalist, more Western-oriented, more unified Ukraine than ever existed before.

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.
