Geographical issues mystify me. We could just have a global court that has absolute jurisdiction here, specifies rules for resolving territorial disputes according to certain basic principles, and stipulates clear provisions for acquiring independence. I know that seems a little naive, no state would surrender so much power. But it seems so much more appealing and reasonable when contrasted with the status quo, where all of these issues are resolved by bloodshed, standoffs, ethnic cleansing, and colliding vessels.
