Keesje - you seem pretty ready to accept turning the clock back to the Argentinian version of pre-January 1833. Do you think that Argentina would be keen to turn things back fully to that time? Try looking up the southern border of the United Provinces in 1833 (Argentina as such did not exist until the 1850's) - about 1000 miles north of the southern tip of present day Argentina.
Look up the "Conquest of the desert". They took territory by force, killing thousands of the original population who had lived there for generations.
In 1833 there were fewer than 100 people in the Falklands. The British evicted a military garrison (of 26 soldiers plus a few wives and children) that they believed to be illegal, and invited the civilian population to remain. Of that population (which numbered only 33 people), 29 of them (including 14 "Argentinians") stayed in the islands.
It seems to be a very "selective" version of 1833 that Argentina wishes to return to.............
