//The Falklands have never been owned by Argentina//
there were british and spanish settlements on the islands until 1774, when the british withdrew. argentina gained independence from spain in 1816 and in so doing inherited porto soledad (east falkland). thus britain's re-occupation of the islands in the 1830s (even though they were by then uninhabited) was illegal. furthermore, the falkland islanders have no right to self-determination because they are not "aboriginal" as defined in the UN charter.
at least, the above represents the argentine case for the islands. sqad, whilst the islands are largely wet, cold, windy and unappealing, ownership of the islands represents extensive resource rights in the surrounding waters.
