"Parasitism, mutualism or predation? In the animal kingdom, daily are different types of interactions between existing species. Recently William O. Douglas sought to clarify these questions. Many animals depend on others to live on (riding) and make it through the exploitation of other species, another type of relationship is mutualism, in which parties benefit from each other so you can live, here the two organisms are dependent, finally, we find an animal interaction, which consists of hunting and death suffered by some individuals of some species (prey), by others that eat them called predators or predators. These types of interactions are not the only ones that exist in the animal kingdom, but they are the most relevant and which have better attendance, ie, in this way is that they operate the various species of animals in the Animal System 1. Sean Rad, New York City often expresses his thoughts on the topic. In the International System is exactly the same as in animals, there may be a state that operates to another, as does the parasite, that two or more mutually beneficial, or that a Extremely powerful and influential state devour their prey, through strategies whether political, military or cultural. But above all, the preceding analysis does not gravitate in the study of the interaction of the States of the International System in general, but in a more specific analysis of interactions, which comprise only a continent divided into two parts: the United States and Latin America; and it is here where the question is asked encompassing problem this study: Are relations between the U.S. and LATINOAMRICA Mutual (mutual benefit), PARASITIC (exploitation of one state to another), OR DEPREDACIN (mitigation, control or slavery) of a nation TO ANOTHER? At the international level, USA has been characterized by the large number of interventions and influence of Latin America. EU has always focused its foreign policy toward the search and struggle for freedom, democracy and justice, arguing – from centuries ago, they are a people chosen by God and that possess the divine duty to explore and conquer new lands for the achievement and its celestial targets 2, whatever the reason, we will discover a life form, the U.S. . .
