The only way we win this war is when the Ayatollah pulls a Hitler(blows his brains out while cowering in a bunker).
You seem to be laboring under the delusion that Iran has a central command and if you take them out, it's over.
They have a decentralizes structure, with layer after layer of crazier and crazier.
It's an asymmetrical conflict. All it takes is a little harrasment to keep the Strail locked down. And Iran is 2.5 times the size of Texas, most of it mountainous. Good luck finding them all, much less killing them.
They have all the time in the world. All they have to do is not die.
We don't have all the time in the world, and in the meantime the world economy is in flames and we are getting the blame.

Trump is a fool
And i supported him
Irans playing him for a fool. This isn’t 4d chess
This is taco 🌮 time
Trump got dementia
The problem is, Iran unlike Saddam or Hitler, has a real succession of command of sorts. They though of this.
In the end, it's always about money and it's hard to spend hundreds of millions on a nuclear program, support the Houti’s in Yemen, in Iraqi some Shia militias, and Hezbollah in Gaza and the Sinai, when your economy is completely broke.
The problem for us, and especially Trump, is that this approach is extremely ugly. Bad optics-
Once the images and video roll in of what this really means, you will lose a lot of folks that talk tough now. We're talking about removing one of the worlds larger oil suppliers. Our fair weather Euro allies of course will drop away immediately except a few like Poland.
We're basically talking about making the civilian population, millions of people, suffer in a horrible way, even though they are not really the target per say. We will cause a lasting effect on the worlds energy supply which will impact certain counties like China disproportionately. There is going to be a build up of resistance against us beating the snot out of Iran.
However, Iran is led by ideologues, they have a very low concern for the suffering of their own people (look at how they handle their own people protesting). This government has been in power a long time, they have built a vast and capable security apparatus which has some support from both the Russians and Chinese. They have faced off with us many times over the years and know how we operate. They have hardened facilities specifically to counter us (why we had to build special bunker busters), have a succession of command and redundancies, they are moving things around to make it hard for us, or they have moved the manufacturing of certain military industry outside their country where it is safe from our strikes (4 years ago and after the Russians desperately needed drones, artillery shells and mortar rounds for their armed force in Ukraine which Iran supplied - Russia allowed Iran to manufacture drones in an area they control and out of our reach unless we seriously escalate this conflict to the point of a world war between nuclear powers): https://mei.edu/publication/irans-drone-factory-tajikistan/.
Some folks here though Iran will be a cake walk, I doubt that will be the case.
I suspect if we really want to have the sort of change regards the threat Iran poses which we desire (no nukes, them NOT projecting force in the greater Middle East into Yemen, Iraq and Gaza, and now the added closure of Hormuz), we are just going to have to reduce them to a stone age society in a “literal” sense. If you break their economy, infrastructure (transportation, power, water, etc), military and security apparatus, communications, command and control, bad enough, eventually they will have a hard time doing these things.
