Meh, whitewashing history is something everyone does. Not like the average British doco on Churchill mentions the crappy stuff he did, or the US doesn't celebrate a genocidal maniac on their bank notes, or the Poles get all knicker knotted about getting partitioned but didn't do it to Czechoslovakia nor stab Lithuania in the back when they were fighting the soviets. And our national myth involves lionising lots of naive chaps going off to die utterly pointlessly in Turkey for the benefit and at the command of imperialist buffoons half a world away.
This illustrates the worst of cynicism.
We should be morally obliged to be mad when people try to revise history to justify atrocitites, just as we should applaud and praise those who shine light on atrocities which have been forgotten or revised in the past. Russia had previously officially apologized for the brutal invasion and occupation of Czechoslovakia. This catharsis was something which strengthened Russia in the global diplomatic scene and gave them increased credibility, especially in Eastern Europe. To backtrack on this is not only an indicator of the increasing disconnect with reality in the Russian internal political scene, but something which will greatly interfere with Russian relations with Eastern European countries, leaving them even more a diplomatic midget, sputtering jingoistic nonsense while country after country in their vicinity comes knocking at NATO's door. At this rate, Belarus will apply for NATO membership in 2017. Sadly, Russia believing that everything that goes against them in the geographical vicinity is a "Western conspiracy" turns out to be a very self-fulfilling prophecy.
You could write a list about every atrocity that has ever occurred, and calculate their awfulness, and see which political entities have the most luggage, and the most undeclared luggage. My perspective is mostly observing that the current state of global affairs is stable, but as things change, this might not be so. So drastic changes are of interest, and keeping track of which way every country is heading is of importance. Most countries are on the path of inceasing awareness of historical atrocities, so it is interesting and noteworthy to see a country heading in the other direction.
You won't find a single country that even approaches frank and honest in their view of their own history. It's not what countries do, at heart they're just like sports fans- we're skillful, honest and brave supporting the bestest team in the entire world; otoh the referee is biased and the opposition are dishonest thugs who dive and cheat.
Challenge me, I have a frank and honest view of the history of my country, which is by and large shared by the general population, to the degree which they are familiar with history of course. Germany has handled Nazism's legacy in a way that almost borders on overcompensation (from personal experience - I have spent quite some time in Germany).
It is true, but typically obvious to the point of being meaningless, to state that everyone is guilty of most crimes to a degree. But to frame it to sound like an equivalence is where cynicism turns to idiocy through oversimplification.
BTW, you should change your avatar to this, it reflects your personality better:
