Abstract
This article discusses the historical efforts for regional integration, suggesting the establishment of the Union of South American Nations (UNASUR) from the perspective of the South American Defence Council (CSD). The hypothesis is that any attempt at regional integration in the area of security and defence cannot be achieved without a consolidated State at individual country level, an acceptable integration of infrastructure in the region, and an pre-existing adequate level of political integration. The process will benefit if the units involved in the integration are more homogenous and more closely related through different political projects in infrastructures and energy.
