I am trying to respond in good faith, but it looks like Hamas is accepted across the world as a terrorist organization for specifically targeting civilians. And as much as I loathe the loss of civilian life at the hands of IDF, this is not a conventional war, and Hamas hiding within civilian populations and tunneling under hospitals is on Hamas and not on IDF. Like it happened in history a million times, Hamas could've surrendered against a superior enemy and and returned hostages, to protect its own citizens.
So, that's why Hamas must cease to exist. Not Palestine itself, nor another government in Palestine - just Hamas. They could've stopped it, they didn't.
Let me know when IDF/Likud behave like this unprovoked (Yes, I know what's going on in West bank and its not remotely close to what Hamas did)
