Sorry but why do you think the islands should not be British?
Because, it is not. It is just a leftover from your colonial history. You will definitely have to leave them at someday, just like you left India, Iran, Egypt, Palestine, Cyprus, etc... If British statesmen are cunning enough, which I sincerely believe so based on my readings, they will try to find a way to take advantage of them just like they did in Cyprus.
I also would like to add I am aware of the fact that no matter what I say, you will keep believing those islands are part of United Kingdom. I do not blame you for this because that's how you have been raised.. It is part of your personality, now. According to your country's beliefs, you are the true source of democracy, modernization and civilization. And you have the mission to show every other country in the world how civilized you are by invading them and getting a pretty small "tax" for what you are going to teach them.
