Er, a little history? the combatants in "The Great War" were prosperous, powerful, "civilised" European nations bound together by a web of treaties. Newsflash, this did not stop them from pointlessly slaughtering over 40 million people in four years of violent conflict. On that note it's even easier for a general or a politician to send mere machines "over the top" than young men. Treaties guarantee nothing.
