But that wasn’t what I have in mind when people say things like “Israel is committing war crimes.” That has a much different connotation to it.

It does have a different connotation to it - as if the gov't of Israel was officially allowing and condoning such "reprehensible behavior" as you put it. However, even if it's against official policy, if the majority of troops are ignoring the laws of their own country's gov't and rules of their own country's military to commit this "reprehensible behavior", then a lot of folks will think that country should be accountable. But this can easily morph to the former statement if one isn't careful about nuance.

I actually meant to say ‘prosecute’ rather than ‘perpetrate’. My bad.

Ah, no worries. Though that word is potentially even more confusing - you must mean in the sense of "pursue until finished" as per https://www.merriam-webster.com/dictionary/prosecute but it also has the meaning of bringing legal action about. Which would imply that the war is legal, which could be stretched further to imply that it's just. Of course, I'd hesitate to go that far on either point (legal or just).

They think this war is just, as you suggest, retaliation for 10/7. But it isn’t. If it were, it would have been more like 2014 - quick, a couple thousand dead, move on.

I thought the same, actually. I could go as far as agreeing that a simple retaliation is legal and just, but since this is not that...

Many people also don’t understand the big picture.

Clearly I'm still not getting it.

That’s pretty standard in war.

That's kind of the problem, though, isn't it?

They think they are experts on warfare and can make a judgment about the morality of the war

Well though, if not the people, then who can make these judgement? Who is empowered to decide this?

Sinwar decided to pull off this attack when he did because he wanted to put a stop to the Abraham Accords.

Agreed. The evidence I've seen so far agrees with this.

Israel sees an opportunity here to seriously weaken the Iranian regime, which will allow the Accords to proceed.

I support the Accords. But I still worry about innocent civilians - such as Gazans and Palestinians who just want to sit this one out and live their lives, or the hostages taken on 10/7. And if the beef was just with Iran, why are these folks getting caught in the middle? (Of course it's not just Iran, Hamas is based in Gaza, but if one can easily confuse the Iranian regime with Hamas, then perhaps it's easier to confuse Hamas with people from Gaza more generally, which leads to innocent civilians being wrongly treated like hostile military opponents.)

Israel has decided they can’t be tolerated anymore.

And no doubt Israel will win this, but I worry about the human sacrifice required from the innocent.
