Interesting... Person below me suggested continuous gameplay additions, but I like the realism of this current state; Geneva Convention is founded and nobody lets anything happen with it... (/J, good mod. LOL!)

It would be interesting if the Geneva Convention had an ongoing gameplay impact to represent the more humanitarian rules of war. Maybe some aggressive actions are considered war crimes and punished by losing happiness, such as razing a city, capturing and killing civilians, perhaps even attacks on cities.
