American citizens have known since 1973 that their dependence on oil puts them at the mercy of every Middle East dictator. The governments have known this clearly since the 1940s - see the Barbarossa operation. The US had literal generations to reduce their oil dependency and yet chose to remain dependent. It has nothing to do with the current war.
replyThe US succeeded in reducing their oil dependency and the country is now a net exporter. That doesn't solve the environmental concerns, nor hermetically seal the country from trends in global oil markets, but the US's energy independence agenda has definitely been successful on its own terms.
replyUnfortunately, it hasn't diminished the number of American foreign policy experts who think it's very important to fight lots of wars in the Middle East.
