The Falklands will be given to Argentina with the U.S. as intermediary to save face. 1) Too expensive for GB to maintain. 2) Monroe Doctrine. 3) We can get something out of Argentina. e.g.. Illegal immigrants in our prisons can be transferred there with Argentina manning the ‘prison’.
Last. The 2000 Brits can be given sheep farms anywhere in the world.
I’m sure that Zimbabwe will welcome them
A small detachment of Euro fighters based on the airstrip would make it too expensive for the Argentines to repeat the invasion. Given that it costs little if anything to base them in the Falklands as opposed to any other RAF base, I would disagree with your contention about the Falklands being “too expensive” to defend.
