Do you not get it? Leasing a Russian Sub to Argentina isn't go to change the situation Argentinas Armed Forces find themselves in, a single battery of S-400 is not going to deny Air Superiority to the RAF who are based on the Falklands at RAF Mount Pleasant and what Russia/ex-Soviet Union did in the FSU has nothing to do with the Falklands.
Argentinas Armed Forces would have to be completely rebuilt before any of this is going to happen-and given the Argentinian President has just annoucened in the past week a bail out package for their economy I seriously doubt they can afford to rebuild their Armed Forces any time soon.
And given that the Falklands fall outside of NATOs responsibilities this is going wildly off-topic.
