These people had not been assimilated into the majority Brazilian society, a fact that worried the government of President Getúlio Vargas. The army had an important role during this process of forced assimilation of these areas of "foreign colonization" that created so-called "ethnic cysts" in Brazil. German Brazilians saw themselves as part of a pluralist society, so that the Deutschtum conception (of being part of a community with a shared German ancestry) seemed compatible with the fact that they were also Brazilian citizens. However, the Brazilian government only accepted the idea of the jus soli, so that all people born in Brazil should see themselves as Brazilians, and leave other ethnic associations behind. The Brazilian view contrasted with the jus sanguinis conception of most German Brazilians of that time, who were still connected to the ancestral homeland. Not only the people of German origin were considered "alien": almost all descendants of immigrants, in some degree, were "non-assimilated", in the opinion of Bethlem and other participants in the campaign. However, evidence of greater resistance to abrasileiramento (Brazilianization) was found in those areas considered "redoubts of Germanism", a situation considered risky to the cultural, racial and territorial integrity of the nation. One of the areas considered "non-patriotic" was the Vale do Itajaí, where the population was composed mostly of Germans, Italians and Poles. In the 1930s, the Vale do Itajaí was described as a place of "strange costumes, full of non-national Brazilians, contaminated by ideals of a nation that collapsed Brazil, a place of disintegration of national spirit". During this period of nationalization, the Germans were considered the most "alien", the Italians closest to the Brazilians, and the Poles in an intermediary position, but none of them were seen as unequivocally Brazilian. The fear of secession was not a novelty in regard to the definition of the Brazilian nation-state: long before 1939, Brazilian nationalists feared the collapse of the South, considering it "too Germanized". Many members of the Brazilian army participated during this process, such as Nogueira: Nogueira also compared the German Brazilians to "an octopus extending its tentacles" in Southern Brazil. Nogueira used the image of the occupation of the most fertile areas of southern territory by foreigners, who had no intention of being integrated into the country, but had remained segregated since the beginning of their settlement.
