This is patent absurdity. What Hamas did on October 7th was an atrocity and a war crime. Many of the perpetrators, and of Hamas military leadership, would be very happy to be able to commit genocide against the people of Israel, and maybe even Jewish people in general.

However, there's no such thing as "unsuccessful genocide". Wanting to commit genocide and even terrorist bombings which target the population you'd like to exterminate are not genocide. To be committing the crime of genocide, you have to actually be in a position where you are actively displacing or exterminating a population.

Israel is committing genocide in Gaza since October 7th, because they are actively working towards a goal of eliminating the Palestinian population from the Gaza territory, or at least from the majority of it. They have already achieved a part of the genocide. They're not going all scorched earth and killing by the millions for the same reason they're not launching one of their illegal nukes in Gaza: they fear international reaction if the move is too sudden and overwhelming.

Hamas, by contrast, is not committing genocide in Israel, because it's not actively killing or starving or displacing any part of the population of Israel. I'm sure Hamas would love to do that, but it's a simple obvious fact that they're not succeeding. This is like claiming that Al Qaeda has an ongoing campaign of genocide of the West, because of 9/11 and some other attacks on, say, British troops.
