Now they're building a wall. Sparta says, hey, if they have a wall, it's gonna be very hard for us if they don't do what, you know, if they start exerting too much influence, it's gonna be hard for us to take down Athens. They instead suggest, hey, Athens, why don't you build a wall? Why don't you build a wall at the Ithmus of Corinth right over here? You might notice the geography of Greece. You have this little, I guess you could call it this little strip of land that connects the mainland, I guess you could say, to this peninsula, this very large peninsula, which is called Peloponnese, which is where Sparta is. And you could imagine that this is a very strategic location.
