Ms Castro clearly has no grasp of democratic principles in any case. The islanders almost 100% wish to remain British. (I only say 'almost' so as not to be accused of exaggeration. There may be a single deluded Falklander somewhere ...)
Now let us examine the logic of 'returning the islands to Latin America as a whole', shall we?
The hispanic conquest of that continent only dates to the sixteenth century and we must be logical, must we not? - Consequently, might I suggest that every country in Central, South and indeed, N. America should be returned to the indigenous indian peoples?
