When did Russia invade Crimea or Ukraine? When did Russia shoot down MH-17? Neither of the competing MH-17 reports accuse Russia of shooting it down. And when did Russia target schools and hospitals in Syria? Some of the hospitals the USA claimed Russia to have bombed have been discovered to be full standing, with no damage, and still in operation. Others have been found to have never existed in the first place.
If you want to look at evils, think of what the USA and its coalition is doing in Mosul, Iraq, where there is more than 2x the average weekly civilian deaths as were occurring in Aleppo, Syria. The whole Western media focus on Aleppo, Syria was a decoy from the much worse state of things happening during the USA-coalition's campaign in Mosul, Iraq. Don't let yourself be so easily manipulated by propaganda and false information.
