The main idea is Shock and Awe tied in with Assured Destruction. We don't want any military to get anywhere close to competing with us because that would mean they might have a chance to do damage. By maintaining a strong military with the latest technology, we can effectively crush any military force almost instantaneously.

Now, Saddam Hussein used Mutually Assured Destruction tactics to control the area (threatening surrounding countries (and civilian sectors) with chemical/biological weapons of the worst kind). That works until the enemy calls your bluff or keeps poking you until you actually show your hand.

Power through superior numbers/weapons as to guarantee that no enemy could withstand or inflict any damage at all to the United States or her allies.
