well one issue at a time the last sentence of the st paragraph truncates the narrative by jumps from one subject internal policy to another foreign policy before falling from the sky after decades to following paragraph without even suggest the reason of s military revolts not to mention that even remotely touches the civilian ones to remedy the last flaw of this paragraph and with citations easy to check in english other section's defect too many sources in portuguese one of them is not even specific to brazilian history and before to deal with the nd paragraph one issue at a time i suggest to let the st paragraph fine and end the discussion about this paragraph i propose that the mention concerning to changes of brazil's boundaries in the early th century even because the border issue of acre in addition to not being the only one of that era contained in itself a military phase among others having not been characterized or reduced to a mere purchase be placed at the beginning of the rd paragraph in the foreign affairs in foreign policy the success in resolving border disputes with neighboring countries in the early years of the republican period was followed by a failed attempt to exert a prominent role in the league of nations after its involvement in world war i more or less eg as i had proposed both with a neutral point of view and specific easily checking citations in english so if you agree to it in relation to the st paragraph i will talk about my suggestions of changes regarding the nd and rd paragraphs and again why of it
