That leaves games. I don't understand that song, honestly. It's based on a TV show where international teams competed in simple games.

Adding some frontiers to those games is probably fine. Also, Peter Gabriel seemed to be implying that games without frontiers had to do with war? Or something? In which case, maybe respecting some frontiers would prevent some wars?
So, my answer is games. Let's give them some frontiers and see what happens.
