Cecil I can not understand how you can make such a mistake. You can look at the census records which were conducted by the French and saw that there were about 1.2 million Armenians living in the Ottoman Empire. So can explain to me that how the Ottomans did killed 1.5 million Armenians.
If we will be talking about genocide and appalling crime and butcherings I would suggest to look at what happened in at the night of February 25 1992 in Khojaly Azerbaijan. Here are some web sites that you can get information and pictures. Also lets not forget %20 of the Azerbaijan is still occupied by Armenia.
