It would be more fair if countries didn't have wars but a Presidential Battle Royale where the presidents are the ones to have to take the risk by getting beaten up, amirite?

This is not a bad idea, Chuck Norris would make a good president, no joke, read some of his think pieces.

This sounds like Animal Farm

Why would that be fair? Then the strongest country doesn't come out on top. The country with the strongest president does.

then that means we would need Arnold Schwarzenegger to run as president
