Book excerpt: The militarization of space began as a rivalry between the United States and the Soviet Union and grew to enormous proportions during the height of the Cold War. Satellite reconnaissance, navigation and weapons guidance, and electronic intelligence comprise only a few of the efforts taken to militarize and dominate space. Today as the prominence of information technology, computing, and telecommunications advances, so does the concept of space as a battlefield. In The Militarization and Weaponization of Space, Matthew Mowthorpe diligently analyzes the military space policies of the United States, the Soviet Union/Russia, and the People's Republic of China from the Cold War period to the present day. Mowthorpe focuses on the development of the ballistic missile defense and other anti-satellite systems and aptly assesses to what degree space will become armed. This work cogently addresses an issue of increasing urgency to scholars of international politics.
