I started out thinking that Russia should be allowed to annex eastern Ukraine to keep European peace intact. I now firmly believe that Putin is insane and that the West should stand against any Russian aggression no matter the cost. And it would be costly. But that is the only way you can stand against aggression like this and the possible future it is the harbinger of- a Europe threatened by Russia when it feels its "citizens" are threatened. These people were acting like animals. It's time Europe woke up.
