Since war is almost inevitable anyway

You don't really get how war works do you

War is fought for land, because everything else that's wanted comes with land (power, resources, tax, etc.) so you can't just plant a war in an arena.

Antarctica. Now nobody wins.

We could call it Warsaw!

That would only favor those who are closest to that place because they'd spend less money on transport.

you mean we put all the fussy world leaders in a large concrete cube and tell them we wish the odds to be ever in their favour?

We have one. It's called the Middle East.

How about this, hunger games with presidents, if they want something they can fight for it, I bet they won't wanna start wars then.

i vote the middle east.
