What about this off the wall idea...Saudi Arabia has calculated that world oil peak is right now, and by refusing to cut production they are protecting themselves from the international backlash? When depletion exceeds new production they will be able to pass the buck saying truthfully that they are still pumping oil as fast as they can.
Meanwhile the tight shale industry in North America collapses and then gets blamed for not supplying the oil the world needs at the start of the down slope. Internationally it is all America's fault, not OPEC.
