There isn't really anything Argentina can do to take the Islands back. They don't have the military might and they don't have political backing. Many of the S American countries are starting to distance themselves from Argentina on this issue. They are even trying to get help from Spain by backing them on the Gibraltar issue, but Spain have their own problems and I can't see them wanting to do too much to piss off the UK at the moment in case they need a bailout. The UK is in a unique position compared to a lot of the other old colonial powers in that they still own a lot of places like this around the world. But I think we have got to the point in history where you can't fight wars over land anymore.
