As Russian troops approach Kyiv, what will happen if it falls? How has the West reacted to Lavrov's UN speech? Will Taiwan be the next Ukraine? Ian Bremmer shares his insights on global politics this week on World In :60.

First, as Russian troops approach Kyiv, what will happen if it falls?

I think it's increasingly what will happen when it falls. I hate to say that. Unless the Russians lay down arms in large numbers because they don't want to fire on their brothers and sisters, the Ukrainians, which is possible and I hold out hope. But it doesn't look very likely thus far. The Russian force will overwhelm the Ukrainians as it is buried upon Kyiv. Look, what's going to happen is you're going to get a government in exile that will either be in the west of Ukraine conceivably, but that's a rump Ukraine that I can't imagine the Russians want, or they move to another country, Poland, maybe France.
