Never mind already back in the 80s and 90s the British population of the Falklands preferred to remain a part of the UK. Nevermind Argentina invaded the Falklands and was ultimately repulsed. No idea where the idea that the Falklands belong to Argentina comes from. The only meaningful population of the islands ever was and is British. Which makes the comparison to HK and Taiwan somewhat pointless, nevermind that Taiw…
Falklands is much closer to Argentina though - they should belong to Argentina by right of proximity.
And where does it end? New Zealand belongs to Australia? Hawaii belongs to Mexico?
In short "proximity" is not how island ownership works.
