You'd think we'd evolve to being able to develop some sort of resource escrow or trust account that takes issues like the oil in South Sudan out of the equation. Allow the U.S. and China to stop worrying about which will gain an advantage on the other, and there for stop the agitation aspect of their external engagements; and also allow the parties in North and South Sudan to stop agonizing over who will gain the lion's share of the revenues.

Instead of arguing over where the line will be, etc, simply agree to the escrow and an equitable system of distribution of product and profits. Keep all the books open source on the web so that a wide range of watchdog groups can monitor. Human nature, greed, lust for power, etc are always in play though...
