Just like the US had the Indian Wars, Argentina had at that same time something that became known as the “Conquest of the Desert”, which involved the seizure of the Patagonia and the pacification (through overwhelming military force, of course) of the native peoples that inhabited it.
In 1971, Argentine comedy troupe Les Luthiers performed a parody entitled “Los noticiarios cinematográficos” (I roughly translate it to “The Newsreel Suite”), which ended with this “sequence” (here, my translation):
CELEBRATION AND PARADE
Under a radiant, sunny day, the citizenry celebrated a new anniversary of the Conquest of the Desert. A parade of airmen, sailors, and soldiers marks the high point of the celebration with the gallant march of our youth in uniform for the defense of our sovereignty.
Closing the parade is a group of descendants of those brave indians that populated the Patagonian lands by the time of the advent of civilization and progress. They are escorted by a troop of mounted police, four assault vehicles, and border guards with dogs and tear gas guns.
