"If there has not been a war in space, there is already more war without space!" To understand the spatial strategy, we must first know the environment and delineate the field. It must then assess the strategic importance of space. Finally, we must imagine the possibilities of a fight since, against and in space. Space Strategy responds to this questioning. Moreover, this book explicitly established concepts, such as the militarization and weaponization of space; it innovates by setting the "martialisation of space". It shows how space assets are a key component of information literacy, the key to power in the next century. Finally, it sets out a number of principles and lays the foundation for a future strategy and using the Moon Lagrange points.
