I feel this time Franek is entirely right.

Besides, Putin OUGHT TO KNOW that trying to bury events of this kind does not work. See the extermination of the Armenians by the Turcs or the British colonial massacres, i.a. in India, or the wholesale extermination of the rightful inhabitants and owners of North and South America, the "Indians". There were no mass media and no TV reports then but all the same... The main result achieved, if any, is rising suspicion and accusations, which then even can become worse than the truth, however embarrassing for Russia and Putin...
