This monograph by Colonel Joseph R. Nunez is a constructive response to the question of "How can the United States best develop security cooperation within the Americas?" In it, he develops the necessary background to make the persuasive argument that it is time for the United States to employ strategic restraint and reassurance of allies to develop a new security architecture that is effective and efficient, not to mention reflecting of our values and interests. The current security architecture of the Western Hemisphere needs major change. To better address current and future threats, the United States must be able to demonstrate the type of leadership that reflects the "soft power" and liberal peace realities of our hemispheric neighborhood. Of course, this will require the recognition and assistance of other leading states that provide real legitimacy and better representation for this new security structure.
