'This book is a fair introductory text to the world of American space security policy for newcomers.' -- E-IR journal
'Joan Johnson-Freese has written a timely, thought-provoking, and richly researched book that should be read by everyone interested in 21st century space policy. She raises serious concerns about our current path and offers recommendations for the new U.S. administration, as well as other governments, for preventing future conflict and strengthening space cooperation.' -- James Clay Moltz, Naval Postgraduate School, USA
'Johnson-Freeses penetrating analysis of space security as a critical component of U.S. national security makes this a must-read book for national security policymakers especially those in the new administration. Her insight provides the context for understanding the complexities of this often underappreciated domain and why "the days of the space sanctuary are gone." In a word compelling.' -- Marcia Smith, Editor of SpacePolicyOnline.com
'Dr. Joan Johnson-Freese makes a compelling case that even under the administration of President Barack Obama, U.S. national space policy has relied too heavily on ineffective, and often counterproductive means in pursuit of overly ambitious objectives. If the United States primary objective is to protect and expand its own ability to use space for a wide variety of highly beneficial economic, military, and social purposes, then the United States should ratchet down its rhetoric and development of offensive capabilities, ramping up its use of space diplomacy deterrence strategies that do not increase crisis instability. This lively book is highly recommended for anyone interested in space or national security.' -- Nancy Gallagher, University of Maryland, USA
'Joan Johnson-Freeses excellent book questions many assumptions made by those in the space policy world as a given and contextualizes governmental decisions (both here and abroad) to allow for a more thorough understanding of the space domain. Through a solid overview of U.S. policy, political statements, and budgetary decisions, she demonstrates how the United States is at a turning point in how it views and acts on space control.' -- Victoria Samson, Secure World Foundation, USA
'Joan Johnson-Freese is an intellectual leader in the much neglected field of space security not just because of her encyclopedic knowledge of the subject but because of her willingness to swim, at times, against the policy tide. In Space Warfare in the 21st Century she has given us an overview of evolution of space policy combined with cogent recommendations for building the sort of order in the cosmos that will be necessary if our species is going to take full advantage of our growing access to space. Her target are those who believe space war is inevitable and our only course is to prepare for it. She argues - with passion tempered by pragmatism - that prudent diplomacy and enlightened self interest can ensure the economic and scientific promise of space for future generations. Readers new to the field will find this book accessible; older hands may find their assumptions challenged; but for anyone interested the future of space, this is a must read.' -- Ambassador Roger G. Harrison, former Director of the Eisenhower Center for Space and Defense Studies
