The OIC needs to finance the UN it has a grip on, since it's basically serving them, the Islamic lobby interests above all

Especially since the 1970, the UN has been the major arena for anti Israel war. This tiny DAVID country targeted by the GOLIATH, in condemnations, etc..

FACTS 

From November 10, 2023: U.N. condemns Israel 8 times, rest of world 0. The UN’s History of the ‘Question of Palestine’ Omits Every Palestinian Attack on Jews. It says, “1936/1939 — Palestinian rebellion against the British Mandate and Jewish immigration.” But not that Arabs murdered Jews, just that it was a "rebellion." It doesn’t say anything about the Arab League boycott of Jews.

Over 20 years ago, Anne Bayefsky wrote (Apr 20, 2024): 'U.N. vs. Israel. Telling standards.':

'The U.N. response to the death of Abdel Aziz Rantissi, and Sheikh Ahmad Yassin before him, exposes a disturbing fault line in the war against terror. Hamas has been declared a terrorist organization by the U.S. State Department, as well as the European Union, Canada, and Australia. The 1988 Covenant of Hamas, the Islamic Resistance Movement, speaks for itself. It begins "Israel will exist and will continue to exist until Islam will obliterate it, just as it obliterated others before it." It continues: "There is no solution for the Palestinian question except through Jihad. Initiatives, proposals and international conferences are all a waste of time and vain endeavors." Its violent message is invoked in the name of defeating the "plan of World Zionism" "embodied in the Protocols of the Elders of Zion." In Rantissi's words of July 2001: "I urge all the brigades to...target the Israeli political leaders and members of parliament..."; "the Hamas political leadership has freed the hand of the brigades to do whatever they want against the brothers of monkeys and pigs." In plain language, the Hamas aim to obliterate the Jewish state is about pure, unadulterated antisemitism.'

Almost two decades later: Daniel Ben-Ami, 8th December 2023: The UN vs Israel. "From ignoring the rape of Israeli women to employing Hamas fighters, the UN is not to be trusted."

GENOCIDE/S?

What has the UN ever done to prevent REAL genocides?

• Muslim Sudan: Since 1956, more than 2.5 million killed.*  Supremacist Arab racist* genocide in Darfur: 2003-5: 200,000; 

• Uganda under Islamic* Idi Amin 1971/79: 500,000*;

• Bangladesh Genocide of 1971 by Islamic Pakistan: 3,000,000* ;

• Cambodia, Pol Pot: 1975 to 1979: between 1.7 million to 3 million*;

• Iraq under Arab tyrant Saddam Hussein since the '70s: Between at least 300,000 * and millions *; 

• Syria, 1982: Arabs on Arab 40,000 in Hama nassacre*;

•  Rwanda 1994: 500,000 to 800,000; 

• Arab Islamic Syria as of Mar 2024: 617,910* including the 1,729, in 2013 by 'chemical' Assad*;

• Or on Arab Islamist attempted genocide (since 1920s with al Husseini coining "itbakh [Adbakh] al yahud" and intensified in 1947), while everyone knows the tactics of "Palestinian" or Hezbollah to bring about their civilian deaths - beginning with Arafat's methods in early 1980s.

FACTORS 

Various factors contribute to UN's war against Israel since the 1970s, including the Arab oil lobby, Congressional Record (Bound Edition), Volume 146 (2000), Part 15] [Senate] [Pages 22562-22566] the Arab huge market as an economic power, Islamic bigotry by religious zealots influencing its politicians represemting Muslim countries, radical liberal agenda pushers (including extremists inside Israel, those making much noise who don't pass the Lynch test (Haaretzism) and plain old racists. 

Who decides on 'human rights' you wonder? This is from a journalist 2021:

I know this is really going to shock all 3 of you who thought Israel was going to get a fair shake, but the 3 members of the UNHRC’s permanent war-crimes probe against Israel all have a history of inflammatory anti-Israel statements and activism.

 Lahav Harkov July 22, 2021  

But above all, the Islamic lobby: 

Islamic countries bloc of over 50 countries dictates much of UN's agendas and appointments, there are 'deals' by counties' officials: we will vote for your candidate if you vote for ours. Which effects at ICC (International Criminal Court) and ICJ (International Court of Justice).. Indeed, the Organisation of Islamic Cooperation (OIC) has 57 members, 56 of which are also member states of the United Nations, with 48 countries being Muslim majority countries. 

(At the UN's inaccurate language it's: "cooperation." SG/SM/21197.

22 March 2022. Ties Linking United Nations, Organization of Islamic Cooperation Based on Shared Belief in Cooperation, Dialogue, Solidarity, Secretary-General Tells Ministers.

press.un.org/en/2022/sgsm21197.doc.htm).

Since the core of the 'conflict' is anti-Jewish bigotry by ethnic: Arab racism and religious: Islamic intolerance... 

CONCLUSION 

Hence, why doesn't the OIC share the largest financial burden on the UN, since it's basically serving them, the Islamic lobby interests above all?
