The UN's definition of genocide, outlined in the 1948 Genocide Convention, refers to acts committed with the intent to destroy, in whole or in part, a national, ethnical, racial, or religious group. These acts include killing members of the group, causing them serious bodily or mental harm, deliberately inflicting conditions of life calculated to bring about physical destruction, imposing measures to prevent births, and forcibly transferring children of the group to another group.
This definition has no numerical aspect, it is all about intent. One person being killed, injured or suffering mental harm is a genocide if the intent was as defined here.
You can make this suit any narrative you want to promote. For the current Gaza tragedy to be defined as a genocide using this definition , the test would be the prove Israel has intent to destroy, in whole or in part, a national, ethnical, racial, or religious group.. So which is it, national, ethnical, racial or religious?
On the other side of this, Hamas has stated intent to destroy and eradicate the State of Israel and its people, as does Iran and all it's proxies. So in the case of Hamas and Iran the genocide is self admitted.
October 7th was an act of genocide under the UN definition.
The Russian kidnapping of Ukranian children would be a genocidal act, the Yazidis have been subject to genocide, the Armenians were etc etc
The genocide " experts " are all putting their opinions forward which as with all opinions does not make them intrinsically correct.
