Well, I think we need to make sure that we have sufficient capabilities in the area to be certain of dealing with any conventional or irregular attempts to invade the Islands or harass its inhabitants or flagged vessels. Whether we have that or not is a matter of debate and I don't feel qualified to pass comments (as mentioned earlier, my gut feeling is that it might be marginal... or perceived as marginal enough for somebody dumb enough to have a go).
We certainly don't need to be sending extra stuff there purely as a 'show of force' because frankly that just gives the Argentinian government political ammunition.
What we *do* need however is a more robust political response. I think it is disgusting that British subjects are currently lacking fresh produce because of Mercosur's refusal to allow FI flagged vessels to dock. It's not far off holding our people to ransom. It's bullying, pure and simple, and bullies who are allowed to have their way grow emboldened.
