The US empire is in deep trouble. It has bet everything on an unsustainable investment of trillions in autosprawl hard assets. Highways, pipelines, ocean tankers, highway tankers, rail tankers, refineries, parking lots, spread out water systems, sewer systems, electrical grid, bridges, and tunnels.
Now they have miscalculated in MENA and cannot guarantee control over the last of the cheap oil, the oil in Kirkuk.They cannot control the transmission of gas from the Caspian to the markets of South Asia.
They cannot care for their own people. They fear rebellion and are working hard to promote racism and other divisions.
This is what is driving US policy. Ignore the corporate media. Turn off the TV.
