In the 1970s they made studies and they showed none S/VTOL fighter will be destroyed easily, the eurofighters are easy pray, in 1982 the Harrier were better because the A-4s did not have AIM-9s and the Mirage did not have AIM-9Ls, but the reality is England only can win if it uses nuclear blackmail, otherwise is the defense of those islands is not easy if Argentina gets Su-34s and PAKFAs, but consider Argentina is not interested in another war and the Su-24s can not win a war just make some political pressure
Considering that the UK regularly stations a quartet of Eurofighters plus a Voyager refueling aircraft, there is plenty of ramp space for additional aircraft. The Eurofighters are kept in hardened shelters, and such is the size of the airfield that runway-denial weapons would be unable to inhibit operations to any appreciable extent. The Eurofighter is a very capable aerial combat aircraft that's extremely well armed with AMRAAM and eventually, Meteor. And in a pinch, F-35B's can also joint the party as well.
Also, the RAF has practiced and homed their skills in long range missions, as demonstrated in Libya.
Furthermore, the UK is capable of rapidly reinforcing the Falklands; a complete infantry battlegroup can be immediately flown into the Falklands within 3 days and a full brigade with their equipment in a few more days to supplement the 1,200 troops already there. Argentina is facing roughly 30 years of the UK planning, training and hardening the defences of the islands, beyond the fact that the British military as an establishment is more professional, capable, and skilled than Argentina's military is.
Argentina's too broke to afford any of the options available, and maintaining any high end capabilities will stretch their budget to the breaking point. They will be lucky to afford trainer jets at this rate. Even a simple barter won't get Argentina very far; you need money to pay for spare parts, weapons, fuel and salaries to maintain any decent level of skill for the pilots, otherwise they will blasted out of the sky no matter what they fly. And that's beyond the fact that the UK has the ability to launch cruise missiles at Argentina from both submarines and fighters at long range.
