Well they started bombing Qatar so they are moving into a direction where they might actually make progress. But to ensure that Hamas is beyond being any kind of threat israel will have to kill everyone in palastine and ensure that iran gets the message that further acts of terror will be responded to in a similar manner.

> israel will have to kill everyone in palastine

Considering Israel is the occupying state inhabiting Palestine, they probably only want to kill the (non-Jewish) Palestinians in Palestine.

But it does seem like they're on the path to your killing "everyone in Palestine" (including themselves) regardless, in addition to causing mass death and instability in many other regions.
