> Genocide is the intentional destruction of a people in whole or in part

That's exactly what Israel is doing from the POV of the whole world but they disagree.

That's not the pov of the whole world. It's actually contrary to the views of all the major Democratic countries like the us, UK and France.

The countries that claim Israel is committing genocide are mostly authoritarian countries.

That's the POV of most human beings, authoritarian technocrats ruling the West are the few exceptions.
