axes of advance. from sumy to the east and to the northeast of the city, it's a new corridor. the convoy we were talking about last week, we are seeing signs it is moving to the west. it takes us to the big picture in town. when you go to kyiv and look at what's going on here, essentially, they'd be facing off against multiple fronts if this comes through. here, in irpin, where we've seen richard engel the last couple days, major humanitarian issues. lots of people evacuating. i'd expect to the west, you'll see the ukrainian army will have to defend on multiple fronts which will dynamically change the situation in kyiv. this will look a lot like a siege, which we've seen in other parts of the country. zoom back out. we've seen this in mariupol, which is essentially surrounded. this is the evacuation from sumy we were talking about yesterday. the bigger picture, some things to think about.
