FO Stout - I think it's a fair bet that if UK had had angle deck carriers with F4 and Bucc in 1982, then the Malvinas would have been left well alone in the first place.
It's worth remembering that Carrington resigned because it was accepted that the sources on the ground were telling the FO that the Argies were revving up, but the FO did SFA. My dad was one of those who had made it quite clear that the invasion would happen eventually (although it took place sooner than even he had forecast), and also one who had to clear up the mess afterwards.
