IMVHO many countries haven't learned a thing: a country must be as much independent as possible. Witch means, since we do not eat oil, having oil might be good, selling it might bring richness but you can't develop only oil, you MUST use produced richness to incentive all the others production you need from food to housing to defense, health etc. Having naturals resources in general it's the same. A State must satisfy it's own basic needs inside it's own borders or it's already doomed. Anything else should be treated as a nice surplus to get more local things.
Autarchy alone is not easy to sustain of course, but tending to it is, and must be done.
