Although I rather support Putin's actions in Snowden and Syria cases, I'm far from believing that he is doing this because he is such a good guy. He needs popularity and support all over the world for very cynical reason: he and his buddies have their families living in Europe and USA, keep their money there, their children are getting education there, they have real estate there etc. They just using Russia as a "milk cow" to gain their well-being, but are planning to live elsewhere. They don't plan in any way becoming an outcasts like North-Korean elite. So some international PR suits their interests very well.
