If any of you think that this war is because of NATO, you are dumb as shit. Every last Ukrainian government was moscow puppet. Previous opposition leader who got major voting force was Viktor Yushchenko - he was poisoned and after that he couldnt reproduce his success.
The real reason why Russia invaded is because Ukraine started to modernize and prosper. Slowly, but steadily. And this is biggest possible threat to Putin. Because if people of Russia could see that their western neighbours, who are just like them, can reduce corruption, can take good use of their resources, can have better lives they will revolt!
