America's New National Security Doctrine by Michel Chossudovsky

In mid-March, the Pentagon released a major document, entitled The National Defense Strategy of the United States of America

This document constitutes a departure from the doctrine of pre-emptive warfare, which has characterized most national security statements since 9/11.

Whereas the preemptive war doctrine envisages military action as a means of "self defense" against countries categorized as "hostile" to the US, the new Pentagon doctrine envisages the possibility of military intervention against countries which do not visibly constitute a threat to the security of the American homeland.
