The Brits couldn’t do it today. They have zero air assets that can fly from a carrier. They have zero strategic bombers. They have 6 Destroyers and 13 Frigates in the entire Royal Navy. They have a grand total of 7600 Marines.
The Brits have simply lost the ability to force an operation again. They can have a few fighters on the Islands, but simply don’t have the range to hit the mainland with anything more than a fighter bomber at the extreme end of its range.
The good news is that the Argies have also basically disarmed too. They don’t have nearly the ability to invade that they did before. Their navy is a shambles. Their Air Force doesn’t have its Falklands war capability.
So its basically a stalemate. An Argentina that cant attack vs a UK that couldn’t dislodge them if they did.
Coming to a USA near you.
