"To this day, the Turkish government refuses to acknowledge the Armenian genocide. This is strange, since the historical evidence of what happened is plentiful. Western observers like the US ambassador in Constantinople, Henry Morgenthau, wrote detailed reports about what was being done - including the telling statement of Mehmed Talaat Pasha, the Interior Minister, that all the Armenians had to perish because 'those who were innocent today might be guilty tomorrow'. Western missionaries too wrote harrowing accounts of what they witnessed. Their testimony formed an important part of the wartime report on 'The Treatment of the Armenians' compiled by Viscount Bryce, who had also investigated the German atrocities in Belgium in 1914. It might conceivably be argued that the citizens of Christian powers already - or later to be - hostile to the Turks had an interest in misrepresenting them. The Young Turks themselves insisted that they were merely retaliating against a pro-Russian fifth column. That was also the line taken by the Sultan in his reply to Pope Benedict XV's intercession on behalf of the Armenians. Yet agents of the Turks' own wartime allies gave the lie to these claims. Rafael de Nogales, a South American mercenary who served as Inspector General of the Turkish forces in Armenia, reported that the Governor-General of the province had ordered the local authorities in Adil Javus 'to exterminate all Armenian males of twelve years of age and over'. A German schoolteacher at Aleppo was appalled by what he saw of the 'extermination of the Armenian nation' and wrote urging his own government to 'put a stop to the brutality'."
