Ban all Russian athletes at Rio - Russian doping

Putin isn’t just the leader of the Russian Federation, he is a 21st century tsar and has wielded power in one form or another since 1999.
Both Time and Forbes voted him the world’s most powerful individual and such is his stranglehold on Russia it is inconceivable that he would not have been at least aware and may even have sanctioned the shocking scale of doping by Russian athletes.
