It's not about Keesje, but the rest of the world, including friends and allies. And no, it won't stop after the referendum the Brits created.
The "Brits" didn't create the vote the Falkland Islanders did. The simple truth is as long as they wish to remain a British protectorate then everyone else can go whistle!
