Yup, Argentina, there's been so many little scuffles over the last 30 years, I lose track of who invaded where

Libya had a bit of a face-off with Egypt, as well as a few other countries, so things got a bit confusing around that time.
[offtopic]As for British Colonies, ask an Australian, to be honest, being a British Colony is little more than a label anyway. The Falkland isles didn't request to be invaded.
The UK didn't contribute to the downfall in the slightest, the invasion of the Isles was an attempt to distract the populace from what was going on, it held no strategic or resource value for either side, it was just a convenient place for both countries to say 'My Dick is bigger than your Dick.'[/offtopic]
As for the main topic, yes, it's a game, that's why we are only theorising, attempting to extrapolate meaning from plot devices as it were

It's always fun, but I gave up expecting it to be fruitful a long time ago

Edit: If you want a rather humorous look into English Colonialism during the Thatcher years, I suggest you watch 'Water' with Micheal Caine, not only is it pretty funny, but it gives a great window on how 'firmly' the British overlook their colonies

Edit: Yup, the Falkand war was '82, all the posing between the US and Libya was only a few years after.
