The Atlanticist-Zionist-Wahhabist axis regards Iran as the primary obstacle to its imperialist ambitions in the Middle East and Central Asia.
To break it down more precisely, it’s a geopolitical rivalry between Saudi Arabia and Iran, and between the kinds of Sunni fundamentalism that originate from Saudi Arabia and northern Egypt (Wahhabism, Salafism, Qubtism) and the Shia. For obvious reasons, the Shia throughout the region are aligned with Iran, but so are plenty of Sunni (particularly in Palestine and Syria) who reject Sunni fundamentalism of the kind being exported by the Gulf States, or who regard Saudia Arabia or (in the case of Hamas, for example) Israel as a greater enemy. Iran is Shia but their leader has called for unity among Shia and Sunni, and the Christian, Jewish, and Zoroastrian minorities in Iran are tolerated and even have seats in parliament (and there are women parliamentarians as well). Plenty of Christians, Alawites, Druze, and others who see Wahhabism, Salafism, Qubtism, etc as the primary threat are also tactically aligned with Iran. Everybody in the Middle East hates the Saudis, even their own allies in the Gulf. The Saudis threatened to invade Qatar a few years ago. The UAE is jealous of its more powerful big brother. The Omanis are Ibadi Muslims who are aligned with the GCC out of geopolitical necessity.
This article from Foreign Affairs (not exactly a pro-Iranian publication) from a couple years ago explains this pretty well:
“Arab elites, grappling with the consequences of an eroding Arab state system, poor governance, and the delegitimization of authoritarian states following the 2011 Arab Spring, enabled Iran and its partners, including Russia, to build a new regional political and security architecture from the ground up. With the support of Tehran as the undisputed center of the axis, Shiite armed movements in Iraq and across the axis of resistance have created a transnational, multiethnic, and cross-confessional political and security network that has made the axis more muscular and effective than ever before.”
Israel is tacitly aligned with Saudi Arabia because they both regard Iran and Syria as their primary geopolitical rivals. The Americans and the British simply want to create network of colonies and client states in the region. As Neal de los Huecos in a thread on my other page, these are the de facto goals of US foreign policy regarding in the region”
“1) Pull support from Hezbollah and let Israel take over Southern Iran, 2) Pull support from the Syrian Druze and let Israel take over Syria, 3) Pull support from the Houthis and let Saudi take over Yemen. 4) Quit all alliances with the Shia Iraqi Govt and let Iraq be the colony it was meant to be. 5) Arrest the Mullahs and bring in the “exiled-to-Los Angeles” National Council of Iran to reinstate the Pahlavi Dynasty.”
Whatever one thinks of Iran, the Iranians are the primary bulwarks against all of the above.
