These types of moves have been standard operating procedures for all the great nations since the dawn of time. The health of the US depends on the trade of oil for dollars, just like the turn of the world depends on energy... This petro-dollar system helps establish the dollar as the world's default currency, and regulates it dominance. If you don't think we are going to eliminate anyone that tries to inject a non-dollar currency as a trade for oil, especially in the middle east, then you live in a fantasy world. That entire region has been destabilized for the benefit of the US for the last 50 years. It's much easier to come in and take (buy, transfer, etc) the oil when those nations are in ruin, then it is when a strong leadership is present. The moment that leadership decides to trade oil for non-dollars, or even worse, under a gold-standard (non-fiat, non-debt system), then you start seeing on CNN and Fox News stories of all the innocent people being killed by "despot" monsters, and all our useful-idiots begin their war chants.
