Neither the USA or Russia wears the white hat. We know Russia's crimes. We are inundated daily with the misery caused.   We see nothing about the "secret" torture centre's the US has throughout Europe. How often are we told of the horrible birth defects and cancers plaguing Iraqis and Afghanis due to the 1000 metric tonnes of radioactive waste left in each of those countries?  Vietnam? Tens of thousands of innocent men, women and children doused in gellified gasoline and burned to death or left to suffer horrible pain the rest of their lives.   What did the perpetrators of these atrocities get?  War medals and praise actually. (google "napalm girl")

You say, This is a man who committed numerous war crimes, who tortured and murdered children, used poison gas against his own people and bombed civilians. 
Can you honestly deny ........ The USA commits/has committed numerous war crimes, who tortured, and murdered children,  and bombed civilians.
