Armenian genocide is not "alleged" in my opionion, it really happened.Some people even clain that Holocaust never happende,and that is also nonsense.
Germany and Turkey are responsible for these serious crimes and genocide but they treat it completely differently.
Germany has accepted historical responsibility for the Holocaust and apologized to Jews but but Turkey denies any responsibility and even denies that it happened at all.
Many countries in the world have condemned the Turkish genocide against the Armenians in World War I.
The genocide of Jews in Germany was condemned by the Nuremberg Trials. The Armenian Genocide in Turkey was not convicted by any court. That makes all the difference! Armenians are afraid to sue.
