We spent a fair amount of time on Ukraine. And I think there's a path that we discussed that we will follow up on in order to try to resolve some of the outstanding issues in order to fully implement Minsk.

America must always be the world's paramount military power. But we can magnify our power through alliances.

No one is going to question my commitment to the defence of our nation. I don't know what it is these Republicans, who didn't serve in any war, have against those of us who are Democrats who did.

I think as we celebrate the 70th anniversary of the UN, it's a good moment to rekindle our efforts to make multilateralism work yet again. And I'm proud to say that in the Iran agreement I think we did show that it can work.

America is the one that has led the effort to strengthen NATO and strengthen the front-line states against Russia's pressures.

We need a new approach to national security - a bold, progressive internationalism that stands in stark contrast to the too often belligerent and myopic unilateralism of the Bush Administration.
