Has anyone ever heard how much of American military expenditure goes directly and indirectly into protecting U.S. energy interests? I know that America has the most expensive military machine on the globe and just wondered how much of its citizens tax money goes to subsidize the price of gas at the pump? Not that I am complaining, because the rest of the world is free-riding, in a sense, off the U.S. energy protection expenditure. Does it add a couple cents to the price of a gallon or is it closer to a dollar? Just wondering.
