US militarism has to be considered under three headings: First, the US military is the largest single consumer of fossil fuel in the world. Second, the US economy, the largest national consumer of fossil fuel in the world, has shown that its primary mode of maintaining a supply of fossil fuel for itself is through military action (assault, intervention, occupation of other oil producing nations). Third, the US military operates in the interest of a corporate economy of which it (the military) is the foremost sector in the US.
