Well... crap.
Yeah, ever since Spain started trying to take Gibraltar from Britain (an island between the two countries) and Britain didn't let them have it, Spain and Argentina have together formed an anti-British alliance. If you don't know, Argentina lost the Falklands War in the 80's after trying to take the Falklands Island Chain from Britain.
Not going to lie, I'm a little worried. While I doubt it would lead to war, but if it did. You know, well, I live in England. I feel this 'Alliance' will probably only aim to give Britain the shaft through loss of trade and the such.
Britain did send ships to Gibraltar on its way to Mediterranean bases to exercise its authority there.

Currently, Britain controls the islands, and it seems that the inhabitants are happy with this. It's worrying when two of the county's oldest enemies may become buds...
