What a British carrier visit to the Falklands would signal

What could Argentina do if a British carrier group visited the Falklands for the war's fortieth anniversary?

Probably protest diplomatically but avoid military action, because the visit would combine Britain's territorial claim with overwhelming local naval power.

A hypothetical British carrier-group visit to the Falklands for the fortieth anniversary of the 1982 war would probably draw an Argentine diplomatic protest and little further action. The example imagines Queen Elizabeth, two Type 23 frigates, two Type 45 destroyers, supply ships, and possibly an Astute-class submarine. That force is judged too powerful for Argentina to challenge locally. Britain would frame the voyage as a visit to its own territory, while Argentina could object diplomatically. The scenario also allows for an invitation to an Argentine ship to join the visit.
