 So, from my perspective, Turkey will continue to play footsie with Russia and Iran on a political outcome. They'll want to have a process that is not owned by Washington that they're a central part of. And that will continue. But they fundamentally diverge from both Russia and Iran on the core question of Assad's future and on what they actually want to see as a political resolution to the Syrian crisis. And therefore, the United States will continue to have the capacity to shape Turkish thinking to engage with Turkey and to come to a better common understanding of what the political shape of Syria looks like in a post-conflict or reduced conflict situation. In order to get there, though, we and Ankara need to get to a better place in terms of our understanding of the Syrian Kurdish issue. And that should be priority number one for us.
