This analysis goes into detail on the situation and reflects on three fundamental factors. The first is an abstraction regarding the new threats, and the definition, perception and impact of such on the societies involved. The second relates to the mission that the various Latin American constitutions assign to Armed Forces and police personnel. The third and last is the model adopted by the EU, and offers a critique of the Central American Framework Treaty on Security, with two extreme poles in the focus that we have undertaken. It ends with a series of conclusions that could serve for reflection or guidelines for at last characterizing the role of Latin American Armed Forces in the fight against the new threats.
