South America, and the Andean region in particular, do not constitute a military or economic threat to the United States, but they are a potential setting for a pax Mafiosa, a tendency toward chaos and disorder. The process taking place in the Andean region is characterized by unstable states (Bolivia, Ecuador), seriously damaged sovereign states (Colombia), damaged democratic regimes (Venezuela) and higher levels of militarization (Colombia, Ecuador, Peru). In addition to inter-state tensions (Venezuela-Colombia, Chile-Bolivia) there are growing transnational security situations (drug trafficking, money-laundering and guerrilla warfare) and social conflicts that arise not only from economic but from identity factors as well. At this juncture, we should reflect on the possibility that Argentina, Brazil in particular and the region in general may find in this list of challenges to citizen and to national security a true opportunity for a converging of viewpoints and a development of policies to endow MERCOSUR with greater substance and identity in political and security matters.
