I am curious if any country has ever admitted to genocide of their own volition without being diplomatically pressured to do so, as a matter of losing a war, sanctions or other not-so-voluntary means?
E.g. the public admittance (for which I am not sure what the proper legal format is) in Germany over the Holocaust as well as other Nazi war crimes didn't even start until about 1970 when Willy Brandt went to the Warsaw Ghetto. In addition to the long term issue of the Turkish denial of the Armenian genocide, a less conspicuous is the avoidance of Serbia (and its big brother, Russia) to acknowledge the genocide in the Bosnian war of the 1990s. Other examples include the massacres of the Natives in the Americas etc etc, none of which have, I believe and correct me if wrong, have been acknowledged as "genocide".
