But you could knock them down a peg if and when they do attack you. With Gorgo your only choice is to become the most hated civ in the game by razzing cities or wiping her out. If she declares war on you that's it, it's like every turn the game rolls a dice to see if you lose today. Your only choice now is lose the war or become a pariah. Playing a peaceful civ? Sorry, better luck next game.
If you're a peaceful civ, just beat her. Her Agenda doesn't say she
never surrenders - it says she won't give you her cities in a peace deal (well, my interpretation, anyway). So if you're playing a peaceful civ and you get attacked by her, you do the same thing you do against any other civ - fight them off until they surrender.
This is true if that even necessitates invading their lands, because again - she'll surrender if you take half of her empire; she's just not going to
give you half of her empire. So if you're in a situation where that is required, like many other civs call upon players to do so - the counter play if you need to invade is to ensure that you pillage as much as you possibly can before you return her stuff. Obliterating a civs army, and then destroying the productive value of half of their empire (pop loss on conquest, totally removed tile improvements, pillaged buildings and districts) will certainly prevent them from knocking on your door anytime soon.
Since you return the cities, the warmonger penalties are refunded, so your reputation in the world isn't damaged.
Literally the only thing this changes is that you can't chip away at her empire piece by piece. Taking a city or two in different wars until you're able to deal the killing blow. It means if you want to strike the killing blow - you need to do it one swoop.
Which will certainly be challenging if you sail across the sea and find a sizable greek empire in the new world. That, I think will make for a very interesting opponent to deal with.
