Analyst points to national sovereignty as an influential factor in Lula's approval Political analyst Brand Arneri stated that the defense of national sovereignty gained relevance during periods of low popularity of the government of Luiz Inacio Lula da Silva (PT). According to him, the president's response to US tax threats on Brazil contributed to improving his approval. Arneri believed that the issue was not central to the election conflict, but estimated that its consequences in the previous episodes prove the importance that Brazilians attach to autonomy and national honor. For the analyst, sovereignty is an issue that needs to be discussed more.
