The thing about this is, while you are right, it also highlights the nature of the dynamic at play. Israel is the aggressor and the one with the power (and cue spiderman, with great power comes great responsibility we like to think). But Hamas has near zero leverage. They engage in a truce or deal, they need to be air tight and buttoned up if they want it to stand. At least that's how I think abou it.
Anything less than 100% compliance can and will open up the threat to throw out the tenous peace. If that makes the ceasefire a fake one or a disingenous one, I guess we all agree. But if it is true that Hamas is playing some stupid game with the hostages, they are the ones who are poking the bear and putting the truce at risk in that instance.
But I guess if the thinking is already one of a foregone conclusion of "israel is just going to blow it up anyways because they don't want the peace" then it's easy to dismiss Hamas culpability in breaking the ceasefire. But I mean, it's a tenous, thin ice cease fire to begin with, you'd think you'd be engaging with the T's & C's with kid gloves and care.
I mean, I gave you my opinion. Israel obviously believed and believes differently.
