The American oil wars are being launched out of weakness, not strength. The American economy is teetering and without control of the remaining oil it will collapse. There will be massive chaos in any case, when only enough oil remains for the American elite and whomever they choose to share it with.
It's not about greed any more. It's about survival. Because the leadership of this country was initially too greedy to switch from oil to solar, wind, geothermal and other renewable alternatives, it may now be too late. Had the hundreds of billions of dollars poured into the invasion and occupation of Iraq been put into alternative energy the world might have had a fighting chance. Now that is far from certain.
