Presently, U.S. border security endeavors are compartmentalized, fragmented, and poorly coordinated. Moreover, international collaborations are extremely limited; success hinges on effective international cooperation. This book addresses U.S. border security management using complexity theory and a systems approach, incorporating both borders and all associated border security institutions simultaneously. Border security research has rarely viewed all stakeholders as a holistic unit up to this point, nor has border security been thoroughly examined using a systems approach. The research in this book scrutinizes the current U.S. border security paradigm in an attempt to determine the systemic reasons why the system is ineffective in securing U.S. borders. Additionally, the research investigates the current level of international cooperation between the United States, Canada, and Mexico. This book increases awareness and will possibly create dissent among established agencies, which is the first step in instituting needed changes that will ultimately increase North American security. The book contends that the establishment of a tri-national-United States, Canadian, and Mexican-border security agency, in addition to legalizing drugs and reestablishing a guest worker program, will be more effective and cost-efficient in securing North American borders.
