Everyone makes mistakes, it's about
learning from them and what you
change to try to make things better in the future.
Generally speaking, the west has been significantly improving the living conditions and human rights protections for its citizens over the last several hundred years, many times in direct response to some horrible mistake that was made and then subsequently learned from (slavery, Vietnam, etc.)
The same cannot be said at all about Russia. All the intelligent, brave people who could see through the propaganda or who had the bravery to do something about it have largely either been killed off or emigrated away at this point. The country has been in a continuous cycle of totalitarian suffering for hundreds of years, with no end in sight.
