"The Bush Administration  apparently thought that their "new reality creation" techniques were so good that they didn't need to have any available force in order to engage in Realpolitik in Georgia."

Not only will the U.S. military establishment now re-reverse their thinking back to conventional wars (recently they have tried to move to a capability based on Iraq-style occupation forces), but the entire NATO project will have to be re-thought. For example, will the U.S. really start WW3 if Russia invades Estonia? I suspect not...
