Energy self sufficiency as a pointer to geopolitical strength

This is an interesting chart outlining energy self sufficiency.  Of course China's self sufficiency is currently strangling their country in killer smogs...as is Indias.  Given that the US has been the number one producer of Oil and Gas for most of history since Edwin Drake drilled the first oil wells in Pennsylvania in the 1860s, it's astounding how good a shape we're in energy wise.  And it's getting better.  We've been blessed with lots of mineral wealth but far more importantly, we've been blessed with a lot of private property with secure property rights that extend to that wealth and the entrepeneurs and engineers to get at it.

It's that Gosh Darn free market tarbaby again.
