Why does genocide occur in areas around the world? Please I need help in this question...

A century since the systematic slaughter of 1.5 million Armenians, and over half a century since 6 million Jews were killed in the Holocaust, mass atrocities continue to take place across the globe, without any sign of stopping. In March, human rights investigators for the United Nations disclosed that the Islamic State of Iraq and Greater Syria’s persecution and killings of Yazidis, a religious minority in Northern Iraq, appeared to be “clearly orchestrated” and gave cause for alarm at a probable genocide.

Explanation:

after defeating german forces in north africa allied leaders turned their attention to "italy," since this was the location that made the most geographic sense before invading northern europe via france.
