At current oil prices there are, possibly, up to $4 trillion in oil reserves under the water about the Falkland Islands. That has to be tempting for anybody, not least a country that continues to trumpet its claim to sovereignty despite getting a bloody nose last time they tried. But they tried because they perceived (rightly) that the UK Government wasn't interested and with planned cutbacks wouldn't be able to do anything about it. With the upcoming SDR and our boots on the ground/ COIN emphasis who knows.....?
Perhaps Gordon B/ Dave might like to consider their 'share' of that $4 trillion (in taxation) & keep just a bit of the deep water Navy & a few fixed wing aircraft, just in case.
As we have built a nice long runway at MPA, the one thing the Argies lacked in '82, it's not an option to recapture the islands, we have to deter them from attempting anything (a couple of C130s & some SF troops would be enough to capture the airfield Entebbe style).
