A diplomacia como parte da Defesa Nacional : a necessidade de integração entre diplomacia e defesa, para a consecução dos interesses nacionais, e o prisma da diplomacia naval do Brasil

Abstract

This thesis aims to propose a comprehensive and integrated analysis of the relations between diplomacy and national defense, addressing both theoretical and practical aspects of these interactions, identifying the benefits, challenges and strategies for a successful synergy between the Ministry of Foreign Affairs and the Ministry of Defense, as well as suggestions for increasing naval diplomacy in the context of the Brazilian Navy. To this end, the work is structured in six chapters. Theoretically, this paper explores realism, liberalism and constructivism. The integration between diplomacy and defense, from various theoretical perspectives, stands out for its ability to combine military force with diplomatic negotiation to achieve national objectives, contribute to stability and promote global security. In realism, it is seen as a strategic form of deterrence and alliance formation. In liberalism, it reinforces international cooperation and peacekeeping operations. In the constructivist view, it helps to see national security narratives. Furthermore, the thesis analyzes how organizations should balance specialization, departmentalization, chain of command,span of control, decision making and formalization to maximize operational efficiency and strategic objectives based on organizational culture and environmental conditions
