I don't understand your line of thinking. The article says nothing about SA and oil because the situation has nothing to do with oil, except as an excuse from Islamo fascists and the rest of the leftist world, to blame America first.
SA doesn't want to change, doesn't want an internal multiculturalism, wants to export their monoculture and is under little pressure to moderate as long as they have the financial means to resist change while propagating their beliefs. The fact that we want to maintain good relations with SA limits our gov't's actions to counter the Islamic push within the US. (Note that the Canadians seem to be seriously entertaining letting their Islamic community begin to apply Sharia law to their own communities.)
Our gov't wants to fight a war without putting the domestic society on a war footing. It's possible that if Iraq works out reasonably well --> change in Syria and Egypt, that eventually Iran, Pakistan and SA may be turned around, but we may not have enough time to let this happen "naturally".
