Marge all Countries & governments throughout the ages have always finally sought recourse through war, sometimes talking just doesn't work, were a poke in the eye will ! From some erbert in a cave needing a bigger cave, grunting didn't work so a big stick did.
The rulers of the middle ages were decided by who could be the most cruel & violent all for the sake of a tatty bit of crown, right through to modern times, but at least now there is a bit more leeway in things such as sanctions & embargoes & the big stick really is the last resort.

The Falklands at the time of them becoming British had nothing to do with oil deposits that is only a recent point that improves their "likeability".
