Idgaf what makes Putin happy. The fact remains that the Crimeans are overwhelmingly happy being part of Russia. This is apparent by polling and the almost complete lack of resistance to Russian forces. Afterall, they've had a few years to launch partisan attacks. They have not.
Free and fair polling! Ha! No, polling based on fear, dude.
Ok. And the lack of resistance? You ignored that part, didn't you? Why aren't the Crimeans killing Russian "occupiers" in their sleep? Why no bombs planted in Russian military vehicles and buildings? The Crimeans aren't resisting because they're HAPPY about being a part of Russia.
