Yeah, but then we would have to convince the settlers to become Argentinians and be part of the wonderful third world, with disastrous governments, low salaries, HUGE taxes, and an overwhelming feeling of being on your own... That's the biggest weapon for the UK.
Yes, I also have no doubts that the Falklands are British by right! I have this oppinion because of some reasons but the main one is that 99,9999999999% of the population WANTS TO BE British
(just not to say 100%) and self-determination
is the most important right of ANY PEOPLE - But politics a part, one thing is sure: an invasion or invasion force doesn't care a bit about what the local population wants or else Argentina wouldn't have invaded the Falklands in 1982, would it?
