This time it's war for oil:
Americans seem to think that the vast increase in domestic oil production from shale deposits has immunized the U.S. economy from Middle East instability. Not by a long shot. The International Energy Agency has warned as clearly as it can that projected low prices of oil in the future depend more on increased Iraqi oil production than on North American shale. And every postwar American recession has been preceded by an increase in oil prices, often the result of Middle East instability.
The cure involves "drone strikes, weapons, reconnaissance assets, targeting assistance, improved and expanded training for his forces, even manned airstrikes."
What could go wrong?
