What's appealing to growing numbers of regimes globally is learning how Israel gets away with politicide. That term was adapted to Israel/Palestine by the late Israeli scholar and professor of sociology Baruch Kimmerling, who argued in 2003 that Israel's domestic and foreign policy is "largely oriented towards one major goal: the politicide of the Palestinian people. By politicide I mean a process that has, as its ultimate goal, the dissolution of the Palestinian people's existence as a legitimate social, political, and economic entity. This process may also but not necessarily include their partial or complete ethnic cleansing from the territory known as the Land of Israel."

The OED defines politicide as "The killing or extermination of a particular group because of its political or ideological beliefs; an instance of this."
So, the venn diagram can include both ethnic cleansing and genocide as means for politicide, and, as Holocaust scholar Omer Bartov argues (among many others), from a historical and legal perspective, ethnic cleansing is often the precursor of genocide.
