Space as a domain and the systems that use it are integrated with American power, whether the soft power of culture, reputation, diplomacy and economics or the hard power of armed force. For that reason, it is no longer possible to stovepipe strategic thinking about space and national security. Developments in one area directly affect others. From civil space programs that help shape foreign spending on space and trade arrangements that impact access to space and have diplomatic consequence to military systems that civilian users have come to rely upon, policymakers must approach developments in space as an integrated whole, a single phenomenon that requires expertise across the range of space activities.
