I don't really see what the controversy is; there is only a finite amount of oil in the world, and industrialisation of China and India is leading to a massive and imminent hike in demand.
Maybe they were worried about peak oil waaaaaaay back in the 1970's - an astonishing 30 years ago so they must have been wrong - but they weren't paying $70/barrel with no end in sight, like we are now. It's apparently already cheaper to invade and occupy a foreign country than it is to buy oil on the open market, so we can look forward to all manner of shenanigans over the next 50 years.
