Most of the ideas that form of the foundation of American defense policy and military strategy today were once new and untested concepts at the far edge of strategic thought. It took thinkers of vision and creativity to give them life and refine them to the point they could be adopted by the defense community and used for strategy and force development. This is a never ending process: new strategic concepts constantly emerge, some fade away, a few pass the tests of suitability, feasibility, and acceptability and make it into the mainstream. To help with this process of identifying those new and untested strategic concepts that merit further examination, the Strategic Studies Institute is publishing a special series called ÒAdvancing Strategic Thought.Ó This provides a venue--a safe haven--for creative, innovative, and experimental thinking about national security policy and military strategy.
