But in any case, if you're saying that in ten years with F35 everything will be fine again, you'd be admitting it ain't OK now. As for the idea that it will take Argentine "at least a decade to come up with something" - that's all right then isn't it!
No, I'm saying they are alright now (In a military sense) as Argentina's military is currently a shambles (Ours arguably is as well- but not nearly to the same extent. They are basically stuck in 1982). In ten years we will have 5th Gen stealth fighters to tackle anything that the Argentine's might have by then. Even then, Argentina has shown very little signs of wanting to re-militarise.
And this is assuming Argentina even wants to try anything on.
Now I agree with you that they are far more vulnerable economically from Argentina. But I don't see how thats something that can be solved militarily, so I don't see why an upping of the garrison is neccesary at this stage. Subsequently, I don't think its good grounds to argue for the carriers at the moment either. IF Argentina starts re-militarising then I might agree.
There are far more pressing concerns then Argentina, and far better reasons to keep a decent carrier fleet then the Falklands.
Even if, against the odds, Argentina did try something on militarily, aside from the current garrison we have got the Astute Class subs which I think is deterrent enough. And after Argentina's experience with the Belgrano you can guarantee that that's something they aren't taking lightly.
