And speculation is that Iran are supporting the Islamic State and that Iran supported Hamas in these attacks.

This isn’t speculation so much as straight up fact.

But we have seen this same kind of radicalization in nations that Israel hasn’t touched in decades (or ever). And most of the “tactics” and players are the same, regardless of which city they are based in.

Absolutely agreed.

We probably would have less pushback (it is not Israel’s responsibility to provide fuel and power to a sovereign country)

While I think a lot of our “what ifs” (even though I agree with you) are ultimately meaningless, I think the value of this right here cannot be overstressed.

Israel had no responsibility to provide power or water to Gaza, full stop. They certainly had no responsibility to provide it once they’d declared war. Palestine being a fully independent country ideally would have put unique pressure on Hamas from existing allies (read: Iran) to actually feed, provide water/power for, and even seek investment (though, obviously, hostile Iranian investment).

From a purely humanitarian standpoint, I see this as an absolute win. Whether it would have truly helped, who knows. My money is where yours is, on no, it wouldn’t have helped.
