Right but the claim predates Argentina’s existence.
The only way Argentina has legitimate claim to the island would be if Spain still maintained the claim to the island at the time Argentina became independent and even then they would have to have to cead the Falkland Islands to Argentina. Which of course never happened.





Proximity matters but only up to a point. The Islands aren’t that close to Argentina, I can’t remember what the exact limit is but under international law islands along to the country whose coastline is closest to them up to a distance of 10 nautical miles as long as there is no claim already in place. Of course that’s an international treaty which historically didn’t necessarily count, which is why you’ve got things like American Samoa and Hawaii.
