But what we've just seen with the Greco-Persian Wars is this Athenian navy is actually quite strong. And in some ways, in fact, in a lot of ways, you could argue that they're the ones that were able to beat off the Persians at Salamis, that the navy was essential there. So Sparta is feeling a little bit threatened, and in particular, they don't like the idea of this wall, because here you have the city-state Athens with this very strong navy. 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?
