As Russia is launching a new phase of war, will eastern Ukraine fall? What is the West's last resort if the war further escalates? With US airlines dropping mask requirements for passengers, is this a bold move? Ian Bremmer shares his insights on global politics this week on World In :60.

As Russia is launching a new phase of war, will eastern Ukraine fall?

Well, first of all, they said they were going to launch the new phase like a few weeks ago. What gives? It's like weeks for the new phase but yeah, they're now really moving into military escalation across the Donbas. Remember, this is the territory that the Russians have declared, recognized as independent. It's about two-thirds more than the territory they had occupied from 2014 until just before the war started, February 24th. And yeah, the Russians clearly have learned some lessons from mistakes that were made in the last eight weeks of the war. They've got new leadership on the ground. They've sent some additional troops, but they also have poor morale. The troops have been depleted and the Ukrainians have an awful lot of military capability. I'll tell you, I think it's very unlikely that east Ukraine will fall by May 9th, which is when Putin wants to make his announcement of victory on Victory Day. I think eventually yes, it's more likely than not that eastern Ukraine will fall, but this is going to get a lot worse before it gets better. And that's a very sad thing.
