President Barack Obama's National Security Strategy was released today and the document shows a shift from the Bush doctrine of unilateral engagement.

Obama's strategy gives more weight to non-military means of achieving security and the new 52 page summary states: "The foundation of American leadership must be a prosperous economy."

The president said that the battle against extremism was "only one element of our strategic environment and cannot define America's engagement with the world."

The report also stressed areas like energy independence and climate change as important security matters that must be part of an overall security strategy.
