The COI issued a 70+ page legal analysis and a formal OHCHR press release summarizing its conclusion that Israel is committing genocide in Gaza. You can dislike the HRC, but the COI is a UN mandated investigative mechanism with its own methodology and evidentiary standards.

> "UN" is imprecise

Fair, but OHCHR hosting a press release doesn’t mean "just staff opinion". OHCHR is the Secretariat for HRC mechanisms, it publishes COI materials. The COI reports to the HRC but operates independently under UN rules for commissions of inquiry. These bodies are designed to feed into accountability processes (state action, sanctions and courts), which is why states and tribunals cite them.

> current HRC members include Qatar, Cuba, and DRC for example.

Yes, membership is political, members are elected by the UN General Assembly but that doesn’t erase the COI’s evidentiary record. And the genocide question isn’t hanging only on the HRC, the International Court of Justice (a separate UN organ) has issued multiple provisional measures orders in South Africa vs Israel, finding Palestinian rights under the Genocide Convention plausible and ordering Israel to prevent genocidal acts, ensure aid and (on 24 May 2024) halt the Rafah offensive. Those are court orders, not HRC opinions.

> "the umpteenth massacre by Israeli forces".

That phrasing came from a joint statement by UN human rights experts (Special Procedures mandate holders) about the 8 June 2024 Nuseirat rescue operation, they were independent experts, not the High Commissioner personally or "the UN as a whole". They don’t bind the UN system, but their statements are part of the record governments consider.

> Who is currently sanctioned by the US for her antisemitism.

Judges from ICC are also sanctioned by US, almost anyone being critical about Israel is either condemned, called antisemitic or sanctioned by either US or Israel. I would like to remind you that US (alone) vetoed multiple UN security council resolutions. And US is isolated relative to most of the world (these below are only the ones I found from the last 3 years, there could be more):

UN General Assembly, Dec 12–13, 2023: "Immediate humanitarian ceasefire" in Gaza passed 153–10–23. US voted against, with a tiny minority of 9 other countries (Israel and some irrelevant little islands).

UN General Assembly, May 10, 2024: Resolution ES-10/23 upgraded Palestine’s participation rights and urged the Security Council to admit Palestine. It passed 143-9-25. US opposed and then vetoed the related Security Council membership bid on April 18, 2024.

Jun 12, 2025 Emergency Special Session (ES-10): A/RES/ES-10/27 149-12-19 in favor. Demanded an immediate, unconditional and permanent ceasefire, unhindered aid access, respect for IHL and protection of UN/NGO workers. The UK and many EU states voted yes, US voted no.

Sep 12-13, 2025 Regular session: "New York Declaration" on a two state pathway 142-10-12 in favor. Endorsed a two state framework that condemns Hamas and envisages a PA led governance track (so "Hamas free"). US and Israel were among the 10 no votes.

There is an obvious pattern here.
