I hardly think the Americans helped bring down the sharia court people because they wanted to protect the interests of some Spanish fishermen or something like that.

The oil stuff seems very unclear, small scale and uninteresting. And it seems to be generally offshore. If it's offshore it doesn't matter if they are fighting a civil war or not as they can't get to the platforms anyway. Compare with the oil offshore Angola (IIRC) during the war.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
