Besides that, what is not known to most expats is that in December 1978 the Argentine Army and Navy almost went to war with Chile in a dispute over three minuscule uninhabited rocks off the mouth of the Beagle Channel, (right across Usuhaia), and some ocean water rights.
Our Navy had already sailed for the attack, but it was held up by a typical stormy sea, thank God.Then the Vatican requested a reprieve of the invasion, and eventually it mediated a ceasefire.
After the fall of Gral Galtieri in 1982, a new treaty was signed with Chile, (who kept the islands), but Argentina kept about 75 % of the disputed waters. Chileans are hated by the Bolivians and Peruvians becausse they ganged up against Chile in the First Pacific War (in 1880), but they both were defeated and lost two provinces each to Chile. The Chilean Army even occupied Lima for a while. In 1801-1803 Chile signed a treaty with Argentina giving away all eastern Patagonia, to secure its left flank against attack while fighting in the North.
