If we can squeeze all the world leaders into 49 square kilometres I've got a much better idea - a private firm could purchase
Bouvet Island from Norway and imprison them all there!
It just so happens to be the most remote island on the planet. Set up 100's of cameras. Kidnap the leaders by drugging them and shoving them on a
boat - provide enough weapons (roughly equal to 1 for every 3 people) not nearly enough clothing / food or shelter and let the games begin



Revenge is best served cold, remote and LIVE LIVE LIVE all day all night all week all year 24/7 (for a fee of course) Last man standing is then king
of the island, by that time we should have a new batch of world leaders for the next exciting season of....... [can't think of a good name ATM]
Now isn't that a much more sensible plan?
