Why could all Muslim countries together not defeat Israel?

Religion hardly plays any “real” role in international politics. Religion is just used by states for their own advantage.

Arabs revolted against fellow Muslim Ottomans with British help which allowed non Muslims (British) to control Jerusalem for first time since Second Crusade. Fellow Muslim countries like Saudis and Iranians are fighting a cold war against each other. For them being a Shia or Sunni is more important than being Muslim. Even Saudi Arabia has enforced blockade against fellow Sunni Qatar. Muslim neighbors Iraq & Iran we're involved in bloody war which was the longest war of last century. Syrian civil war, Afghan Civil war, wars in Yemen etc. have often demonstrated that Muslim countries put their own interest above religion.

There is no unity among Muslim nations. Saudi Arabia is more inclined to defeat Iran than Israel. It is alleged that Egyptian Govt. asked Israel to drop bombs on terrorist positions inside Egypt. Even in 1948 only 5 Arab countries attacked Israel when the New Nation was born. Jordan secretly wants to control East Jerusalem and territories which they lost in 1967 war. Pakistan is more interested in setting it's own scores with India than fighting Israel. And Arab kingdoms need American support to consolidate their own power.

I have not see a single statement by any Muslim head of state against persecution of Muslims in China. So when they can't issue a statement against China then how can they unite against America backed Israel.

A. They wouldn’t be able to. The Israeli military is more powerful than theirs are.

B. Israel has nuclear weapons just in case.

C. They don’t want to. This isn’t 1948, and most of the Arab nations have no desire to destroy Israel and no sympathy for Hamas. Hamas is part of the Muslim Brotherhood, which threatens Arab governments and has been particularly troublesome for Egypt. Hamas is a proxy of Iran, along with Hezbollah and other bad actors. The Arab governments see Iran and its proxies as the real threat, and Israel has quietly become an ally. The Arab countries have quietly been establishing diplomatic relations with Israel for some years now, with Saudi Arabia next on the list.
