There was a book out a couple years ago about RAF planned bombing run on Argentina airfields. Never happened. But as Dan Rather said,”...it could have happened that way.” LOL!
The “Black Buck” missions, with RAF Vulcans bombing targets on the Falkland Islands (trying to cut the runway at Stanley with bombs and taking out Argie radars with Shrikes) were designed in part to let the Argies know that the RAF could go after mainland targets, if Maggie Thatcher asked it to.
Remember that the invasion of the Falklands was intended to shut down domestic social unrest by creating a unifying “rally ‘round the flag” effect that boosted national pride. So there were definitely social tensions before, and most certainly after, the Falklands War. Including the June 1982 riots cited above.
