I think you are confusing Genocide with assisted dying which is the case here in Palestinian terrorists Gaza. A genocide is appropriate to describe what happened in Rwanda where over 100 days 800,000 Tutsi were murdered while the UN did nothing to stop the killing.
In Palestinian terrorists Gaza HamAss, their affiliates and supporters initiated a brutal attack on Israel while the UN took active roles either fighting Israel in Gaza or activating kangaroo courts. Since Gazans have elected terrorists to run Gaza while carrying a war to destroy Israel Israel response at best gently slapping them on their wrists.
