Actually, there hasn't been evidence of Russia cheating in the olympics, so far - which is why The International Bobsleigh and Skeleton Federation has just reversed its ban on Russian athletes, saying “There is not (yet) sufficient evidence against the athletes that would justify the provisional suspension."

Regarding hospital bombing, so far, it is only the USA and USA-backed extremists who are proven to have bombed hospitals. In fact, the coverage of Aleppo in Western media was only meant as a diversion of attention from Mosul, Iraq, where the USA-coalition's campaign has been causing more than double the average weekly civilian casualties as were caused throughout the campaign for Aleppo.

Also, nobody accuses Russia of downing MH-17. There are competing reports, one which was a partisan effort and included West Ukraine, while dismissing the report form the maker of the Buk missile, which concluded that the airplane was shot down from West-Ukraine controlled territory.
