This memorandum posits and critically analyzes several apologies, motivations, and principles contributing to Mexico's increasingly active foreign policy role in Central America. It sets out a series of explanations including those typified as socio-cultural, historical, and ideological, economic, political, and strategic/security. In each case, the author proposes the argument and then exposes it to analysis, featuring its strengths and weaknesses. The several categories define distinct and distinguishable parts of the larger foreign policy matrix and their proposition and elucidation contributes to an enriched understanding of the formulation and articulation of Mexican policy in Central America. In this effort, the author is not concerned essentially with the substance of Mexico's Central American policy, but rather with the motivations and principles informing the policy (or policies) and the apologies devised to explain Mexico's activities in the region.
