I don't agree with everything he says, but the Pope is right about the Armenian genocide. From Wikipaedia:
The Armenian Genocide (Armenian: Հայոց Ցեղասպանություն Hayots Tseghaspanutyun),[note 3] also known as the Armenian Holocaust, the Armenian Massacres and, traditionally by Armenians, as Medz Yeghern (Armenian: Մեծ Եղեռն, "Great Crime"),was the Ottoman government's systematic extermination of its minority Armenian subjects inside their historic homeland which lies within the territory constituting the present-day Republic of Turkey. The total number of people killed as a result has been estimated at between 1 and 1.5 million. The starting date is conventionally held to be 24 April 1915, [emphasis added] the day Ottoman authorities rounded up and arrested some 250 Armenian intellectuals and community leaders in Constantinople. The genocide was carried out during and after World War I and implemented in two phases: the wholesale killing of the able-bodied male population through massacre and subjection of army conscripts to forced labour, followed by the deportation of women, children, the elderly and infirm on death marches leading to the Syrian desert. Driven forward by military escorts, the deportees were deprived of food and water and subjected to periodic robbery, rape, and massacre. Other indigenous and Christian ethnic groups such as the Assyrians and the Ottoman Greeks were similarly targeted for extermination by the Ottoman government, and their treatment is considered by many historians to be part of the same genocidal policy. The majority of Armenian diaspora communities around the world came into being as a direct result of the genocide.
Raphael Lemkin was explicitly moved by the Armenian annihilation to coin the word genocide in 1943 and define systematic and premeditated exterminations within legal parameters. The Armenian Genocide is acknowledged to have been one of the first modern genocides, because scholars point to the organized manner in which the killings were carried out in order to eliminate the Armenians, and it is the second most-studied case of genocide after the Holocaust.
Turkey, the successor state of the Ottoman Empire, denies the word genocide is an accurate term for the mass killings of Armenians that began under Ottoman rule in 1915. It has in recent years been faced with repeated calls to recognize them as genocide. To date, twenty-two countries have officially recognized the mass killings as genocide, a view which is shared by most genocide scholars and historians.
Pope Francis described it as the "First genocide of the XX century", causing a diplomatic incident with Turkey. The bishop of Romedefended his pronouncement by saying it was his duty to honour the memory of the innocent men, women and children who were "senselessly" murdered by Ottoman Turks 100 years before he became Pontiff. He also called on all heads of state and international organizations to recognize "the truth of what transpired and oppose such crimes without ceding to ambiguity or compromise."
