United States of South America

A nation which formerly controlled much of Central and South America in the Cosmic Era, and collaborated with the Atlantic Federation in the construction of the Porta Panama mass driver. Before the outbreak of war, the United States of South America had aligned itself with the PLANTs and made arrangements to covertly exchange shipments of food and manufactured goods, and it refused to join the Earth Alliance once open hostilities began. On February 19, C.E. 70, Alliance forces launched an armed invasion of this nation, and its territory was annexed by the Atlantic Federation.

After the First Bloody Valentine War ended, the USSA sought for independence, resulting in the South American War of Independence. The most prominent figure of this war was Edward Harrelson, an Earth Alliance defector, who was critically wounded in his last battle against Earth Alliance ace pilot Rena Imelia. When the Junius Seven Treaty was negotiated, the USSA became independent again but it does not have central america in it's iand area anymore. However when the second war started the USSA again allied itself with the Earth Alliance.
