Why the Falkland Islanders determine the sovereignty dispute

Why is Argentina unlikely to regain the Falkland Islands?

The resident population chooses British status, and ignoring its right to self-determination undermines Argentina's legal and political case.

The abstract legal history of the islands differs from the political reality created by a long-established civilian population and functioning government. Without residents, competing historical claims might remain a difficult international legal dispute. With residents, arguments framed as decolonization fail when they disregard islanders who repeatedly choose their existing British status. Argentina would have to change the population's preference through a sustained hearts-and-minds effort rather than treat the people as irrelevant to sovereignty. The 1982 invasion makes that persuasion exceptionally unlikely while those who experienced it, or their close descendants, shape public memory.
