Genocide is often referred to as the crime of crimes, but what is its legal definition? And how will the recent genocide cases against Israel and Russia at the International Court of Justice impact the conflicts that the countries are involved in? We discuss these and more questions with genocide scholar Professor Caroline Fournet. She outlines the limitations of the genocide definition, possible differences in how the International Court of Justice and the International Criminal Court use the term genocide, and why the ruling of these courts can be useful, even when it's not visible right away.
