Illicit networks affect everyone in our modern, globalized world. From human trafficking in Eastern Europe to drug smuggling in East Asia, to the illicit arms trade in Africa, to terrorist cells in East Asia and insurgents in the Caucasus, transnational illicit networks have tentacles that reach everywhere. The trade in illegal narcotics is perhaps most worrisome, but of growing concern is the illicit trafficking of counterfeit items, weapons, natural resources, money, cultural property, and even people by shrewd, well-resourced, and nefarious adversaries. I have experience combating these threats personally at the tactical, operational, and strategic levels. As a young naval officer on a variety of ships, I spent a fair amount of time patrolling the global commons where transnational criminals in the guise of pirates and drug smugglers proliferate. I was in the Pentagon on 9/11 and personally experienced the global reach of modern terrorism.
