If they are one people, then all of Russia is also Ukraine. And I happen to think Zelenskyy is a more legitimate leader.

I wonder if there’s a localized zone where there is some sort of really great density of people who consider themselves Ukrainians. And I wonder if there exists some distinguishable boundary between them - culturally, societally, dare I say politically - where on one side an individual would expect to encounter a Ukrainian, versus on the other side, where they would more probably expect to encounter a non-Ukrainian?

Edit: Maybe an edge? A ridge? Something that describes a clearly defined boundary between two distinct areas that are closely related in many regards while also being clearly distinguishable based on the split that defines the division between said areas…

Edit again: I swear it’s on the tip of my tongue. So frustrating. A line, maybe? That seems closer, but not quite there.
