Jack,
Yes she sent the task force to retake the Islands and I applauded her for it at the time but there is no getting away from the truth that the UK had previously announced the withdrawal of all UK military presence from the area and this was interpreted as a green traffic light to the Argies.
I'm not a conspirator but I'm not a liar either, UK knew that the Argies were seriously disputing the islands and until the invasion her government didn't give a sh1t about them in favour of saving a bit of money, UK had even announced the retirement of HMS Hermes which became the task force flagship, just how many green lights did Argentina need?
