By allowing the US to develop its own energy resources, even the 90% bought by Europe would decline drastically. Mind you, I'm not just talking about oil. We have enough proven oil and gas reserves to last 600 years according to an article posted on TH today. But we have enough thorium to supply all of our electrical needs for the next 3000 years.
Cheap nuclear power will put an end to the importance of the Middle East on the world stage. And it is within our grasp. The US built a thorium reactor decades ago, but because it did not breed components for nukes, it was not viewed with favor at the time. But we need government and the "environmentalists" to get out of the way and let people go ahead and develop it commercially.
