Due to certain nation’s reluctance to adequately stand up against human rights abuses
In countries like the US, despite recognition by the vast majority of states, the federal government still maintain a position of denial. This is not only a head in the sand approach to human rights violations, sending out a mixed message over human rights, but it also flies in the face of democracy, as the overwhelming scientific, historical and public opinion is being ignored.
However, many of the nations that do not recognise this genocide may themselves have a questionable human rights record, and therefore not deem the subject as historically significant. For example it would be hard to imagine countries such as Iran, Saudi Arabia, or China, who regularly disregard human rights laws, taking historical Turkish genocide seriously. Likewise, many other known violent human rights abuses are ongoing, such as Duterte’s support of extrajudicial killing in the Philippines, or even many ethnic hostilities in African countries such as Mali and Sudan. It is hard to see regions such as these calling out Turkey historical war crimes, when they are themselves still engaged in their own.
