Precisely McGrath. And Ringer, the point was well made at the time that Thatcher reduced UK naval presence in the area in the knowledge that this might provoke an Argentinian adventure. Do you think the UK foreign office was unaware of domestic politics in Argentina?

A quick check (as I should have done earlier) reveals that the "rejoice" episode was in response to UK helicopters attacking a different Argentine battleship, the Santa Fe (thereby paving the way for a land invasion). It was not in response to the Belgrano, but it was certainly not in response to the securing of overall victory either.
