The document discusses Brazil's lack of sovereignty due to its economic dependence on foreign capital and technology as well as its lack of military and nuclear power. It argues that Brazil is not a sovereign nation because over half of its large companies are foreign-owned and it has little control over its economy. Additionally, without nuclear weapons, Brazil could become a victim of invasion by larger powers seeking to exploit its natural resources like water and oil. The document concludes that Brazil currently lacks both economic sovereignty and the ability to ensure popular sovereignty for its population.
