But while U.S. military planners look at target lists, Iraq and Gulf Cooperation Council (GCC) states see only risk.

“They may like to see the Iranian leadership weakened, but all of them are more concerned about a scenario of chaos and uncertainty and the possibility of more radical elements coming to power there,” Anna Jacobs Khalaf, a Gulf analyst and non-resident fellow at the Arab Gulf States Institute, told Al Jazeera last month.

Since January, Saudi Arabia, Qatar, and Oman, alongside Turkey and Egypt, have been engaged in intense diplomacy to pull Washington and Tehran back from the brink. This is not because they harbor any sympathy for Tehran, but because they realize they would be on the front lines of the Iranian retaliation, and what happens after if the regime were to collapse.

Even if the Gulf states were to be spared Iranian strikes on their territory, there would be other devastating consequences. These states are trying to diversify their economies and attract foreign investment and talent; a threat of regional war would send capital and people fleeing.

A potential refugee crisis is another major fear. The Iranian port of Bandar Abbas is a short boat ride from Dubai. A conflict that devastates Iran's economy or triggers internal collapse could send thousands of displaced people across the water to the UAE.

Then there is a risk of an economic nightmare. As Iranian officials have explicitly warned, all options are on the table in the case of war, including blocking or mining the Strait of Hormuz. While a full closure is unlikely as it would severely harm Iran’s own oil exports to China, the IRGC Navy is now preparing a "smart" closure — selective interdiction that targets Western-linked tankers while allowing Chinese oil purchases to pass, Yemeni Houthi rebel style.

One-fifth of the world's oil passes through that strait. As happened with the Houthi blockade of the Red Sea in response to the Israeli attacks in Gaza, the threat of closure will send insurance premiums skyrocketing and raise global oil prices.

Don't get me wrong, I'm extremely opposed to a war in Iran for no fucking reason, in large part because I give a shit about the well being of the Iranian people and want to see them make their own way out of authoritarian theocracy without western intervention. But I'm not exactly sure what more radical group could possibly come to power there than the Ayatollah. Is ISIS-K a serious enough political entity that it could end up wielding any actual power in the aftermath? Cause I don't see anyone else who could be much more radical (while maintaining something resembling a state) than what they've already got.

Real reason: The economic nightmare for OPEC of an Iran that isn't a pariah state.

The Taliban?

And it might encourage resistance against the oligarchic dictatorships and despotisms that rule those countries.

The Taliban are hardline Sunni. Same goes for ISIS. Iran is overwhelmingly majority Shi'a. Won't happen. The Iranian people are not going to replace a dictatorship by homegrown religious fanatics by one run by foreign ones with no cultural or religious connection to Iran.

Not saying the Taliban could take over, but more along the lines of is pretty easy to imagine something else for the Iranian people lol

Given we're talking about Saudi fucking Arabia, by "radical" they mean "radical against me", not "will behead more homosexuals than us". They're probably afraid any ally to the US regime would be open targets for the Iranian military, and try to appear peaceful
