that invaded another country
Could you give us
the fucking proof?
Like this one that came out just an hour ago?
http://time.com/3198068/russian-soldiers-in-ukraine-put-pressure-on-putins-denials/Or the pictures of captured Russian POWs? Or the fact that Crimea is not part of Ukraine any more? What proof do you need to believe that Russia invaded Ukrainian soil?
and started a war
You need to learn this subject better. According to ukrainian "authorities" there is no war, there is "anti-terrorist operation".
They're just saying that to get US attention and support. Everyone else recognizes it for what it is, a civil war, started by Russian propaganda, fear mongering, and invasion.
And now they're blaming Russia for referendum in the Crimea, what a joke. Despite the fact that no one used armed vehicles to disband the government and parliament of the Crimea, and no one was put in jail there.
Are you sure about that? Because Russian style freedom is on the move already
