This is a bit misleading.
Israel proposed that it maintain absolute and total military control of Gaza, but that a "peacekeeping force" from three Arab nations, bizarrely to be controlled by the US, would "secure food distribution".
Israel has absolutely zero intention of handing over control of Gaza, and has gone to extraordinary lengths to vilify and delegitimize every international organization at every turn.
An actual peacekeeping force as described above would be about keeping Israel in check as much as ensuring Hamas doesn't re-appear.
The charter for Hamas for years called for the total destruction of Israel. That's been recently removed, but their actions haven't changed.
Why would any nation allow such a government to be their neighbor? The best that anyone could hope for would be a North / South Korea or CCP/KMT divide, but those only work because both sides share a common identity.
It’s time for aggressive outside intervention.
It has a series of Basic Laws that serve that function (they are expressly a solution to the failure initially to pass a Constitution and are intended to be compiled once complete into a Constitution), but while some of them are problematic on grounds that touch on the Israel-Palestine conflict, I don't think any of them call for the destruction of Palestine (which isn't to say that most Israeli leaders since Israeli occupied the West Bank and Gaza haven't done something like that, but that's a different issue than the Basic Laws doing it.)
Given the history of Israel with the UNIFIL...
If the answer is "None" then Israel did not in fact propose peacekeeping forces.
Hamas didn’t counter with a preferred peacekeeping composition, they rejected peacekeeping to retain their monopoly on violence (and Gaza’s resources).
To the extent there are evils in this story, they’re the leadership of Hamas and Likud.
I didn't claim Isreal set forth a realistic peace keeping plan, you did. And you failed to bring the receipts.
What you say here is the equivalent of Russia proposing to Ukraine that the war could be ended if they install the Russian National Guard as peace keepers in their country and then saying: "But Ukraine didn't make a counterproposal".
Yes, because that kind of proposal is an insult to the intelligence of everybody who has to read it. And your point about Hamas means you're waving the flag for one of the war parties here and thus have an entirely untrustworthy position anyways.
Let me clarify: If a party to any war proposes a peacekeeping force that is already fighting in the war, it is not a credible peace offer, period. A credible peace offer involves a peace keeping force that is seen as neutral enough by both sides of the conflict.
This is fair. My point is Hamas has shown zero interest in an international peacekeeping force in Gaza. A lack of enthusiasm possibly only matched by the nations that would have to provide said force.
