The Falklands conflict was almost half a century ago. It is doubtful that the UK could respond today like they did in 1982.
The video "The Navy With More Admirals Than Warships"[1] addresses that exact scenario, and talks about the current woeful state of the British Navy today.
I think that’s somewhat unclear. In principle, the new carriers with F-35s should have a much bigger advantage over the Argentinian navy and air force than the tiny carriers we sent to the Falkland’s with Harrier jump jets. But of course it is impossible to know until such a thing actually happens. (Even in the case of a far more antecedently plausible conflict such as Russia/Ukraine, expert predictions were all over the place, and mostly wrong.)

You are right to question who your allies are.
