The decline of the United States’ hegemony is provoking an intensification of the competition with China. In light of this, we observe the emergence of middle powers (key states), as a result of their location and relative potential, and regional influence. These key states contribute to facilitate or limit the intervention of the major powers in regional spaces. Of these middle powers, Brazil is perhaps the most paradigmatic. With a remarkable hard power potential, Brazil has no declared enemies, internal ethnic conflicts and not known, no significant border conflicts, and above all, no major historical rivalries with great powers. Brazil appears to live in a ring of peace, facing the South Atlantic. In this chapter, we argue that Brazil holds the ability to decisively influence the South American subcontinent, particularly the South Atlantic Ocean. Therefore, the leading question of this research stands as: will Brazil be a “velociraptor,” a key state, capable of being a promoter of stability in South America and the South Atlantic? To do that, Brazil will have to explore a number of geopolitical axes, using its enormous capacity of attraction—its soft power—and developing what we call “sweet and smart geopolitics.”
