::Personally, I'm happy with your drafted paragraphs. It's well sourced and there's no original research there so I don't see it how it could be judged as biased. Within the article we already mention the UK's viewpoint so Argentina's viewpoint definitely needs to be mentioned. If you went ahead and edited that in then you'd see no opposition from me. I'd suggest you go ahead and do so and removed the NPOV tag and see if anyone has anything to say on the edit. Thanks,
