Luis Moreno Ocampo, the inaugural prosecutor of the International Criminal Court, has classified the ethnic cleansing of Nagorno-Karabakh Armenians as a second Armenian genocide, and opined that the inaction of the international community encouraged Azerbaijan to act with impunity.[34][35]

The number of deaths has nothing to do with it. The intent is the same, the only difference between the two genocides is that they were less successful at killing people in the second one. The only people that are helped by defending a distinction between ethnic cleansing and genocide, that does not exist, are the people who want to commit genocide.

Your argument’s defense of a nonexistent boundary between genocide and ethnic cleansing boils down to genocide denial. There is no agreed upon definition of ethnic cleansing. There is no way to peacefully forcefully relocate a group of people. An attempt to forcefully relocate a group of people is motivated by the desire to destroy that group in whole or in part.

The quote from the wiki article points out everything I have now written down in this comment. It’s written as a series of rhetorical questions with clear answers. Your argument’s effort to misrepresent the wiki page’s descriptive analysis of ethnic cleansing as an official definition is an attempt to police a none existent boundary. You argument left out the last part of that section.

Multiple genocide scholars have criticized distinguishing between ethnic cleansing and genocide, with Martin Shaw arguing that forced deportation necessarily results in the destruction of a group and this must be foreseen by the perpetrators.

A call for ethnic cleansing is a call for genocide. There is no way to engage in peaceful forceful deportation or population transfer. There is no meaningful difference between getting rid of a group by forcefully removing them and destroying them.

The Armenian genocide involved death marches, into the desert without food or water. What’s the meaningful difference between sending people to die in the desert and destroying them? There isn’t one.

I found this quote useful so I’m going to put it here as well as it seems incredibly relevant.

https://en.wikipedia.org/wiki/Ethnic_cleansing

“How could ‘forced deportation’ ever be achieved without extreme coercion, indeed violence? How, indeed, could deportation not be forced? How could people not resist? How could it not involve the destruction of a community, of the way of life that a group has enjoyed over a period of time? How could those who deported a group not intend this destruction? In what significant way is the forcible removal of a population from their homeland different from the destruction’ of a group? If the boundary between ‘cleansing’ and genocide is unreal, why police it?”
