Wow Stuart agrees with me, that is unusual! Although I disagree with your points about our government. Sure I hate it as much as the next British man, but it's still one of the finest in the world. Compared to Argentina whose government I don't know much about, but don't appear to be good rulers for the small islands according to the island's residents.
And despite losing our allies to the Argentines, that's including USA (so much for our help with Afghanistan and Iraq), we are still able to take on Argentina on our own as the 1984 war proved. For every four Argentine soldiers we lost one British soldier, I'm sure in 26 years we haven't suddenly become the worst army ever. So military wise is not a problem. Diplomatic wise I'm unsure, but we have good reasons to keep the islands as its the residents of the island's wish.
