Surely if a ship leaves an Argentinian port for the Falklands', then it is fair game for the Argies to scream & shout about, but the chances are an Argentinian company was standing to make money from any shipment & shipping business?
However if a ship bound for the Falklands' from ANY OTHER port, South American or not, is sailing in international waters & is stopped, boarded, searched & confiscated by the Argentine Armada, isn't that tantermount to piracy?
4 more Tyffies, 8 GR4's with Sea Eagles, 4 Nimrods, an extra tanker & a pair of AWACS, another Sub, a Frigate, a Destroyer & an RFA tender should be sent to MPA on an 'Exercise'. I'm sure the Americans can cover our NATO obligations in exchange for an oil deal or 2 & HMG should get it's finger out & build the airfield on TdC that the islanders want... just in case...
