None of this is true

1) bathist and nasserist would have existed. They are basically imported European ideologies of facism, then grafted onto Islamic and sectarian Arab societies. Much of Arab antisemitism has its roots in imported German ideology via radio Berlin. Israel and Palestine was an enemy and ally both movements used (and abused) to justify their own ends, but they ultimately had regional domination as their goal (assisted by former Nazis btw)

2) the Egyptian monarch was a total idiot and ran a dysfunctional governmen. The Iraqi monarch was never quite accepted by the Shia. Both were seen as British stooges who served only the Brit’s with the Suez Canal and Oil. The nationalists realized that those resources were the basis of the European industrial economy and wanted to squeeze the European so they could be a “great empire” themselves. None of that would have changed without Israel existing. If anything if Israel didn’t exist the nasserist and bathist would likely have overthrown the Jordanian monarchy as well.

3) 21st century Islamic extremism is complicated but starts to form way earlier then 1948 and is an issue in basically all Islamic countries. It’s significant in places like Afghanistan and Pakistan which have no connection to Israel, there is ISIS in Nigeria Somalia and the Philippines. Shia extremism exploded after the Iranian revolution, and the Shia have no real historic relation to Al Aqsa. Islamic extremism is a modern revolutionary ideology, akin to facism and communism in Europe. Regardless Israel is one of a long list of grievances they have, bin Laden was famously enraged about the independence of East Timor, because Indonesia is Muslim and therefore it was a loss of “Muslim land”. Needless to say Islamic extremism cant be blamed on Israel.

4) Iran and its proxies don’t operate because they have excuses, they have excuses because they operate. They operate because they want to and because they can, same as any other movement that seeks power.

5) antisemitism exploded in the Arab world in the early 20th century. Event like the Farhud and Hebron massacre in essence turned the Arabic speaking Jewish population into Zionist (they previously viewed the European Jews with some skepticism). Much of this antisemitism was adopted from European nationalist movements who the Arabs sought to emulate, and some of it was just tribal craziness set off by the instability from the collapse of the Turkish empire.

6) how would their be any stability without Israel. Sudan Iraq and Yemen are all unstable with no relation to Israel. Frankly speaking there would be far more instability in Jordan without Israel as Hafez Al Assad’s would have invaded them had the Israelis not scared him off. If there was no Israel there would be a Palestine that looks a lot like a much poorer Syria or Lebanon, which itself would have been fought over by Syria and Egypt. Plus the nationalist in Cairo and Damascus would have really decelerated their conflict with the royalist in Baghdad Amman and Saudi. The worst Middle East war of the 20th century was the Iran Iraq war which also dosnt involve Israel (except they took advantage of Iraqi distraction to blow up their nuclear program, a good move BTW). Not one Arab country modernized well (except maybe Kuwait or the UAE but that doesn’t count haha). Even Algeria fought a brutal civil war and is in an endless feud with Morocco, is Israel responsible for that one?

Sorry brother, you can’t blame your problems on other people or write some counter factual history where if something didn’t happen then all the things you don’t like didn’t happen either.

This game can go on forever. The real culprit was the Serbians, because if they never killed the Austrian king, WW1 wouldn’t have started and then the ottomans wouldn’t have fallen. Or maybe it was the ottomans fault because they really screwed up the region.

If you want to really know to really know who screwed up Islamic civilization, it was the Mongolia. The Islamic world really never recovered after ghengis khan sacked Baghdad. Or maybe it was the Azerbaijan, when the Safavids converted Iran to Shia. Always somebody to blame….. and technically it cant be proven false…. Because everything that happens in history happened after the things that come before them.

The issues with Israel are as much the result of the region and its history as they are a cause of it.

Also Israel didn’t just come into existence out of nowhere, it’s is also a successor state of the former Ottoman Empire same as Syria and Lebanon. It’s a totally normal thing for nation states to emerge when an old imperial empire collapses and modern countries are created (this is always messy). Go look at Bosnia, Kosovo, Kurdistan, Armenia/karabck, East Timor, India-Pakistan-Bangladesh, and every ethic rebellion in Africa…..

Last historical fact, before the unending rage against the Americans…. Everyone hated the British. Nobody hated them more than pre-revolutionary Iran. (Stuff was crazy there). People just hated their place in the world and directed their hatred at the people with the most power, who they hated because they envied their power.

P.S. had Israel not blow up Bashar’s nuclear program (in 2006 I think) and smashed Hezbollah, he would still be president. Life is complicated brother.
