That's rather obviously been one of Israel's primary goals from the start - to destroy as much infrastructure as possible, to create as much hardship as possible for the Palestinians.
And rather obviously, that's in service to their longer term goal of taking full and direct control of Gaza. They want to render it uninhabitable, so that they can cast their planned occupation as a practical or even humanitarian necessity, rather than what it in fact is - brazen, and brazenly illegal, conquest.
The central point to keep in mind as far as all of that goes is that Netanyahu and his hard-right cronies have, at every turn, entirely rejected a two-state solution and any form of Palestinian autonomy. To just the degree necessary to maintain a PR facade, they claim that conquest is not their intent, but if it's not going to be a two-state solution, conquest is literally the only alternative, so it is and can only be their actual goal, and their claims to the contrary are and can only be quite simply lies.
And not coincidentally, the wholesale destruction of Gazan infrastructure in which Israel has self-evidently engaged fits right in with that interpretation.
Yes.
Broadly, the whole situation is only murky and complex if you grant some credence to Israel's rhetoric. If you start with the presumption that Netanyahu and his hard-right cronies are lying and that conquest has been the goal all along (and not just from the beginning of the current hostilities but for years now), then everything falls neatly into place and it all makes perfect sense.
That's certainly not a coincidence.
