I think and this is only a suggestion...we should allocate a certain PART of the planet to war. Think of it like going on vacation. When ever two or more countries want to war it out they go to this part of the world specifically designed for warfare and battle it out. This way there's no damage to the participating countries..in fact we could even bet on it like the World Cup's...they could broadcast it on the TV's too!

It will be called War Zone! ufff i'm so intelligent my brains hurt.
