I am not really qualified to judge on the verity of the article, but the statement that's there is no strong "integration" between the US government and the gas and oil industry (and other ones for that matter) is absurd. The US fought wars over access to cheap oil (Gulf war 1) has put extremely lucrative deals for their own oil companies into place after forcing regime change (gulf war 2), has highest officials transition to highest jobs in industry (Cheney), has shown multiple times that it will use intelligence apperatus for industry advantages (the spying scandal in Germany, airbus vs boring contracts...). Many (most) US military operations over the last 30 years can be directly attributed to economic motivations.
