Not to be too pedantic but I think you'll find it was the Junta's actions and Mrs T's reactions, rather than the other way around!
Erm, possibly Nott? Long-regarded as the other villain of the piece, the-then Defence Secretary tendered his resignation at the same time as Lord Carrington, but the ‘Iron Lady’ didn’t accept it. Maybe a guilt reaction as historian Piers Brendon records it was herself rather than Nott who “plucked ‘the Red Plum’ of Antarctica”, HMS Endurance, to save c.£3 million per year, allegedly referred to the ice-patrol vessel as, “a military irrelevance”, vehemently supported the savings and briefed against her fellow Cabinet member as being too timid.
That signal, amongst others, had much to do with the junta’s subsequent actions. By comparison, the present shameful acts re Ark Royal and the Harriers must look like a gift-wrapped invitation to reach for the old 1982 amphibious landing files and have another go? In their shoes I’d wait til the cutting torches have completed the rest of the RN Fleet downsizing exercise and then kick-off. As ever, should it happen, it won't be the politicians who'll pay with their lives.
