Potentially dangerous in that if the Argentines were to capture him, they could ransom him for the deed to the Falkland Islands. Just my take. ;-)
Pffffttt! Do you think that the present-day Argentines, with their ditzy President and tanking economy, are in any sort of position to claim themselves to be a Naval superpower of any kind or able to capture the Heir to the British Throne for ransom? Highly unlikely.
During the actual Falklands conflict, Maggie Thatcher was in a direct war with the Ruthless Argentine Military Dictator Galtieri, and Maggie ended up winning.
