The definition is destroy. If Hamas hadn't attacked on Oct 7 then Isreal would have carried on with containment. If Hamas stand down and release the hostages Isreal would act differently. The fact that ceasefire negotiations are progressing shows Isreal will accept a solution other than killing everyone.
If you want to accuse Isreal there is plenty of stuff to choose from. Using words like Genocide and Holocaust is a deliberate way of denying Isreal's right to exist.
