Yep. It's always about power.
Vietnam was, according to a Green Beret roommate of mine, all because of the oil in the Mekong Delta. A fact that the then America supporting press neglected to mention.
I've seen reference to it exactly once in the MSM, a mention in passing in a boat people sob story about how they had to black out and very quietly slip by the drilling platforms to escape.

Don’t forget Lady Bird Johnson’s Rubber Plantations!

Actually they did mention the oil from time to time, but never made much of it.
