You forgot to mention that another war ongoing for 8 years now was also started by Putin.
And when things go to court, like with MH17, all the evidence points that it's russia and its puppets is killing civilian families.
Evidence? That sounds like an understatement to me, we have details history of the whole thing including communication with command and photos of the route the BUK took afterward going into Russia. Its beyond shadow of doubt it was russian military that is responsible for MH17
So it's OK to kill civilians, your own civilians, in a war, if it was started by somebody else. Good to know that.
