The "oil wars" are products of people who lack the intelligence or patience to negotiate. And besides, it's stupid to kill one another for it, when even the "winners" lose in the end.

We run into a problem when demand outstrips supply, and if we're not quite there yet, we're exceedingly close.
Time to stop fighting over what's left, and start putting the world's collective brain-power toward figuring out how we're going to continue in a post-oil environment.
