Ok, I was mistaken about that one piece. It doesn't help your case.
One of the citations from that line on the wiki page has
> Haim Yelin, head of the Eshkol Regional Council, added: "Everyone criticized Israel for the weapons it's been using, but we must realize that the other side is using illegal weapons."
So, yes, people including Israelis claim that the use of WP is a chemical weapon and illegal.
You get how taking unexploded munitions and sending them back over is a different thing than using them originally in the first place, no?
I searched the wiki page for that quote, since it doesn't mention chemical weapons, and it doesn't appear to exist on the page. Do you mind providing a reference? Weapons — and certain uses of weapons — can be "illegal" without being violations of chemical weapons bans.
I admit to being a bit suspicious that this quote claims anything about "chemical weapons." What the international community has criticized Hamas for, as per the wiki page, is indiscriminately firing rockets at civilian areas — which is illegal. They used white phosphorus in the rockets as well, but even prior to that, as per the wiki page they were filling rockets with TNT and explosive fertilizers, which use their chemical properties (of explosion) to kill people too. So if chemical properties of lighting on fire count as "chemical weapons" (they don't though), I think the chemical properties of TNT would suffice as well.
As per numerous [1] articles [2] and sources [3] the international community does not even consider Israel to have ever revealed owning chemical weapons (although it is suspected that they do); if white phosphorus was considered a chemical weapon, there would be no question: Israel has publicly used it, and publicly admitted to using and owning it [4]. Your claim is just incorrect.
Edit: even the Human Rights Watch article you linked disagrees with you! It criticizes Israel's use of white phosphorous because it violates international law on indiscriminate weapons use — the same laws Hamas broke with its rocket attacks — and specifically says that white phosphorus is not considered a chemical weapon. Quote:
White phosphorus is not considered a chemical weapon and is not banned per se. But like all weapons its use is restricted by the fundamental principles of international humanitarian law: it must be used in a manner that adequately distinguishes between combatants and civilians, and it may never target the latter.
I think this is the end of the discussion. Even the sources you have tried to provide contradict your claim that Israel used "chemical weapons" on Gazans.
