Well, and that power can be abused as well, particularly for a military that relies on fossil fuels as extensively as the US. Additionally, there's not just the "classic" way of fighting wars (i.e. shooting stuff and blowing up stuff), but there's also economic warfare - and hiking the price of a vital good in war is an extremely effective weapon.
