One thing for sure, it's not going to look like Russia invading Ukraine. The Iranians don't have the resolve or the support or the capabilities that Ukraine had and has. It will look more like Iraq in terms of the ability of the military to put up any resistance.
The problem with "boots on the ground" isn't that it can't succeed. The problem is it has zero support from the American public. People feel about this a lot more strongly than the other topics dividing the public.
Polls after the 12 day bombing campaign in 2025 showed that 60% disapproved the bombing. That means you probably have at least a 40% base of support for active overthroing, growing, to change the regime, which is larger than the current supporters. Maybe you could have done something with it. Wait until the previous Komenei died of his cancer instead of martyring him, and wait for the new nomination and the protests that would follow to strike (decapitation of the morality police, species to open the prisons, etc).
The way it was done just feels like the US wanted chaos and death, not meaningful change.
The US will be bogged down for years at a minimum if we entered Iran on the ground, or we would lose quickly and tuck tail.
This isn't a fight to be won in a conventional war, the administration put every chip they had on a gamble that regime change was possible with air superiority alone. I don't know of any historical example of that working, but I guess we'll see what happens.
The challenge is that regime is large and armed and they can hide and weather the storm. They'll hide in hospitals, and mosques, and schools and amongst civilians.
Getting them and disrupting their organization to a point where a popular revolt can take over seems ... lessay hard.
What needs to happen is that some parts of the military, who are a bit less fanatic, switches sides. The probability of that is very hard to gauge. There are stories of some defecting but hard to know if it's true or not.
Personally I don't see how an air campaign alone can lead to any regime change we'd actually want to see. We are all being told the Iranian public is a cohesive unit with a strong majority wanting to go back to 1978, I don't buy it.
The only likely outcomes I see, if the regime is changed at all, is a military coup with even worse people coming in, a very bloody civil war, or a faction in the country we never hear about taking over quickly by promising the world to the public. For the last one, I'd expect that to be a group more akin to the Nazis than some group that actually means well for Iranians.
Got it.
I'm not seeing any parallels.
There can be some "rally to the flag" effect but the Iranian population by large is not going to suddenly like their government.
But to turn the story around a little. Do you see Americans rallying around Trump if the Iranians attack some high profile US targets?
(Btw, the only recent documented instance of machine gun mowing down people is Saudi police mowing down Somali workers).
60% of the Iranian population polled were against the bombing during the 12 day war, bombing that, unlike this one, didn't break too much civilian infrastructure (targeting desalination plants is something I thought even Russia wouldn't do, but well, I shouldn't hold US army and Tsahal to the same standards). And that's with most observers saying that only 20-25% of the population support the regime in 'normal' time.
You had thousands dead, 50k people in prison waiting for the death penalty, a leader on his deathbed, and rather than waiting for the internal tensions between army branches to break the regime, the US chose to martyr the almost dead, suffering leader, consolidating his successor power, and eliminating and opposition in the more laical army. Nice fucking job. Now the army and the clerical police are aligned.
Even when you organize and plan correctly a regime change, a few unlucky breaks and you create a Lybia. Going there gung-ho was truly a spectacular choice, and managed to put Komenei son in place without any power struggles that could have been instrumentalized.
Then they need to drive the rest out of the country, and then keep them out forever, regardless of whatever chaos, instability, and misery arise within the country.
You can't build a stable, prosperous country with remnants of a former regime periodically showing up at people's doors holding guns and telling them that they're now part of a resistance movement.
