The world is about to experience the greatest geopolitical transformation in at least the past three generations. The United States’ need for oil has greatly diminished, and its goals in the Middle East have changed. The United States now views the world wholly in relation to its other interests. Global and local demographics, new outsiders in the area, and a new contest shaping up between Iran and Saudi Arabia contribute to continuing instability in the Middle East. A global energy crisis could soon draw many countries into the Middle East, and a simultaneous political crisis could erode state authorities there, unleashing a new wave of violence and terrorism. ... The United States is transforming into a country with global reach but no global interests. For the 4 billion people on this planet who are utterly dependent on global trade for their well-being, this transformation is possibly the worst outcome imaginable. ... Even if the United States was convinced that its economic and physical security required international engagement, it is about to step out to lunch, and it is going to be a very, very long lunch. Just as the rest of the world needs the United States, it is leaving the building.
