It occurs to me that the United States spends a whacking great amount of money each year on it's military. Including, but not limited to, research and development. Is it possible (at a subconcious level) that some of the U.S.'s current international deployments may be (partially) as a result of having to justify this massive use of resources?
Or indeed (again subconciously) as a means of "field testing" it's new assets? To ensure that, heaven forfend, she ever has to do battle with someone capable of fighting back.
