Armenian genocide denial
During the time the genocide was happening, Enver Pasha, told Ambassador Morgenthau (the American Ambassador to the Ottoman Empire) that Armenians were separatists (wanting to create their own country on Ottoman Land), traitors (people who betray their country) and violent towards Ottoman soldiers and that was why the Ottoman government had to displace them. This was untrue, Armenians were only violent after the genocide had started.
