Major M. V. Smith's Ten Propositions Regarding Spacepower is an important contribution to the spacepower literature. Within weeks of being written, an early draft found its way into the various colleges around Air University's Academic Circle. Within months it reached colleges and universities across the United States and even the international academic community. Major Smith's work begins to quench the growing thirst among those seeking to understand elements contributing to spacepower. More importantly, it offers a view of what spacepower will mean for the United States in the coming decades. I believe Ten Propositions Regarding Spacepower will live up to its aim: assisting political leaders, military professionals, and interested citizens to understand better the nature of space as a source of national and military power. It is a "must read" that belongs at the very top of your reading list. Lance W. Lord General, USAF Commander, Air Force Space Command
