Ian Bremmer's Quick Take: The Putin-Trump call, some 90 minutes long, now over. And I would call this a win for both sides, for the Americans and the Russians, and not horrible for Ukraine and Europe, but kicking the can on what's going to be some big problems down the road and setting out where those challenges are going to be. Why is that?

Well, first of all, Putin said, "No," to the 30-day complete ceasefire, but did give a win to Trump, having accepted a 30-day ceasefire with no conditions with the Ukrainians. The Russians are saying they're prepared to do that, with no gives, as long as it's about targeting energy infrastructure, and in principle, still some discussions around maritime attacks around the Black Sea. Places that frankly the Russians have been irritated with what Ukraine has been able to do with air drones and with sea drones. And also allows the Russians to continue to press for territorial gains over the course of the coming weeks, depleting Ukraine's military capabilities. Plus, the weather's getting warmer, how much damage are you going to do to Ukraine, how miserable you can make them when you're no longer dealing with the freeze is not quite as relevant. So, not a particular loss for the Russians.
