The Rover Conventions
Commenter "Sergey" has contributed a wonderful piece of folk wisdom about international law and its enforceability:
In old Russia there was a proverbial Yiddish saying on usefulness of formalities of law in dealing with those who do not respect law: "Scribe mit a Hund a Dogovor" (sign a treaty with a dog so it would not bite you).
Yes, indeed. Dip Rover's paw in the ink and have him sign on the dotted line, and I'm sure everything will be just fine.
