Asides the usual eye-poking going on back and forth...
I was re-reading the Wiki write up on the Falklands, as well as the show on it on the Military Channel. What I found interesting was you had two very stretched forces trying to adapt their tactics.
The Argentinaians had A-4 Skyhawks that didnt allow for much loiter time at all. Get in, get out. Much the same for the Mirage aircraft they had. And of course, the very few Exocet missiles they had.
The British simply had Harriers and choppers. The Harrier proved its abilities and did well.
And of course, the naval aspect of the fight. Both sides took heavy hits. The British sank that old cruiser with a nuclear sub. The Argentinians sank the HMS Sheffield with an Exocet strike.

As to now...I think this would be a fools war on the part of Argentina. Its a clear case of trying to confuse the public and detract attention from core problems. The British would mop them up quickly if they tried. I doubt they would need the help of the USA for this. Lessons have been learned on deploying to worldwide scenarios.
