The burden of proof is on the country that started an unprovoked, brutal war of aggression that has thrown away the lives of hundreds of thousands of people in just over a year and still insists on not referring to it as a war. If you don't want people to believe that your country is a brutal oppressive authoritarian regime, you start by not acting like one, not by crying foul when people tell stories about your brutal oppressive authoritarian habits.

They'd love nothing more than for you to believe there is no proof or evidence for anything -- no truth for you to discern. Just struggles in the will to power.
