I have just spent 7 weeks in Argentina, basically going from bottom to top. Being very English, I was a little concerned about any aggro I might face I needn't have worried. Apart from a few signs saying "nostra Malvinas" or something a little more grammatically correct, there was almost no evidence that there had been any conflict at all. Only twice was the subject raised - once I was thanked because that little escapade destroyed what remained of the military government's credibility and allowed a relatively bloodless counter coup and the restoration of a democratic system, the other saying that they couldn't run their own country let alone some god forsaken islands in the middle of the Atlantic.
The people were delightful - but Argentina is an object lesson of what happens if you allow politicians to rise above the law. Incredibly rich in natural resources, they lurch from one economic crisis to another thanks to inept, corrupt and powerful politicians.
If anyone wants a bit of adventure, try Argentina. Just don't behave like Clarkson - the people had no choice. A military government who "disappeared" 100,000 people plus conscription left no option for the soldiers. They died, the govenment didn't and doesn't care and the scars of that are all too easily rubbed off from their families and friends. Tact and sensitivity are all that are needed and you will have a ball, regardless of your nationality. IMHO!
