This conference featured 103 Foreign Defense and Military Attachés, Law Enforcement Attachés, and Diplomats representing 67 countries. The conference theme was Borders & Security: Similarities, Differences, and Shared Affinities. This conference explored a wide range of topics to include border control/management, trust, corruption/transnational crime, development of public support for education, a whole-of-government/whole-of-nation approach, and dealing with the unique challenges a border “ecosystem” presents. The concept of an ecosystem captures the complex dynamics whereby permanent residents and stakeholders of a border region increasingly interact with flows of humans, goods, information, cash, and other commodities. The degrees of permeability along any given border are best managed by information exchanges, policy coordination, and operational collaboration among all affected nations.
