Let's agree to disagree on this.
Do you believe Hamas will be destroyed? Even massively weakened? I certainly don't.
Hamas is a dictatorship. They are extremely well funded yet very little is spent on governing Gaza.
Hamas was actually elected initially. It happened as part of a strategy by the Netanyahu government to divide and conquer, propping up Hamas to weaken Fatah and make it impossible for the Palestinians to negotiate as one and thus scuttle a two-state solution.

How do yo deal with a dictatorship who cares little about the people they govern? Who's sole purpose is the extermination of another race? Who launches indiscriminate terror attacks? And does all of this whilst happening to be your nextdoor neighbour.
That's the thing, though. Gaza isn't their next-door neighbour in a geopolitical sense. If they were, the Gazans would actually be able to operate like, y'know, a country. They cannot. They are, by design, completely dependent on Israel for all services. They cannot leave or export or import goods without Israeli approval, their power, food and water supplies are regularly suspended at the whims of the Israeli government, and the civilian toll from Israeli attacks on Palestinians vastly exceeds that of Palestinian attacks on Israel.
If Gaza was their next-door neighbour, these things would constitute declarations of war. Given that Gaza is not a country, though, they're just collective punishment: a crime against humanity.
And if you think that further brutalizing them is going to end the attacks, then, I mean, there's the whole of human history to point at of that failing miserably. People do not generally respond well to being brutalized.
The brutal truth is the humanitarian crisis in Gaza is created and used by Hamas to provide justification for their actions, to generate income for their cause and to get support from Western countries. It is not in their interest to see things get better and so they don't.
I'm sorry, this is grossly inaccurate. The humanitarian crisis is caused by Gaza being an open-air prison where 2m people are fenced into a tiny space with zero resources or means to better themselves. Their houses can be, and frequently are, razed to the ground or simply taken at any time, for any reason, both in Gaza and in the West Bank. Yeah, being the third generation imprisoned in that fashion makes people a mite unhappy with their jailors.
