The national strategy of the U.S. is changing in response to the demands of the Global War on Terror.

Reports of budgetary warfare suggest that the balance of spending is tilting towards the Army and the Marines, and away from the two more mobile and strike-oriented services, the Navy and the Air Force. While it is too soon to say how these changes will play out, it is possible to describe the forces at work.
