How do these guys decide which "betrayals" are "unconscionable" and which are, you know, just business as usual? Throw darts? Is there a Magic 8-Ball in the Oval Office, official dice at 10 Downing Street, and a deck of tarot cards in the Élysée Palace?
Truth is, a couple decades ago, the UN got a a 1,000-piece puzzle of a map of the world for Christmas. Every now and then the Security Council gets it out and puts it together, just to take some time to relax and hang out together. Someone always steals one piece at the outset and hides it, and wherever the hole ends up, that's the country that's been naughty this month and must be punished. They take turns figuring out who took the missing piece, and then they all have a good laugh and go get milkshakes before they rock-paper-scissors for sanctions or out-and-out bombs and bullets.
