One reason for this expanded naval role already is apparent. Under such circumstances, the ability of naval forces to get where they are needed and to stay as long as needed is essential. Naval forces are the visible guarantee that the United States can and will react to provocation and will support its friends in time of need. There is, however, an even more exciting prospect. That is, we can use naval presence to foreclose an enemy's options entirely.
Naval forces can deter by demonstrating that any aggression, large or small, is doomed to failure.
No matter what a foe's intentions or how much he may strive for a swift military fait accompli, he would be forced to recognize that our forces can deny him his objective, defend against his threats, and bring sufficient tailored power to bear quickly enough to prevent even temporary success. Deterrence also depends on the power our allies can bring to bear. Enhanced forward naval forces will build such deterrence in two new ways. We will provide potential partners an offshore air and missile defense against an aggressor's threats and thereby enable them to freely join us or grant access to our land-based forces. And we will use our technology, especially our battlespace awareness, to help them help themselves by multiplying the impact of their forces and lending a new dimension to what they can do in battle.
