United States strategic planners are carrying out a fundamental reconfiguration of America's military presence throughout the world. The shift came to light in November 2011, when President Barack Obama announced that some 2 500 US Marines would take up permanent positions at a training base on the northern tip of Australia. It was underscored in January 2012 when the president appeared at the Pentagon for the release of an extraordinary guidance document with the striking title 'Sustaining United States Global Leadership: Priorities for the Twenty-First Century Defined'. The revised strategic posture earmarks more US military resources to East Asia in general and the South China Sea littoral in particular.
