Your argument makes sense, but it starts with a very flawed assumption: that Iran wants to dominate the world. The reality accepted by everyone except the US and its few allies on this issue is that Iran is an extremely defensive country. The current regime, and the country in general, feels threatened in the region, being generally sorrounded by belligerent hostile countries, with the backing of the US (Saudi Arabia and Israel being the most powerful and the most belligerent).

So, if Iran wins, what will actually happen is that Iran will be left alone to function just like any other non-democratic state. Is the regime bad for its people? Yes. Is it better than being at war? Absolutely.

And regarding nuclear weapons, Iran has declared numerous times that it would gladly participate in an agreement, enforced by UN/IANA inspectors, to declare the entire region a nuclear-free area. Israel is blocking any such agreement. Iran has entered deals with the US and other western countries to renounce its nuclear weapons program in exchange for lifting the embargo and other kinds of help. The US has backed up from these deals twice now. The second time, they have not even claimed to have any evidence that Iran is not respecting the deal; and the other parties to the agreement, like the entire rest of 'the West' have in fact remained in the deal, as has Iran, despite the new US sanctions (deemed illegal by the UN).

This is a bit simplistic, isn't it? First, the one between Iran and USA doesn't have to be a zero-sum game. Why is it a matter of states winning or losing? I don't recall Iran waging a war against the US, or trying to destroy civil liberties in the West. For example, with the nuclear agreement, both Iran and the US (or Europe) would have benefited- why did the US got out of it then?

Second, the two sides in this game are not necessarily Iran with its model of society and the US with its own model of society. The US is a free and democratic society, but that doesn't mean that their geo-political goals are all about freedom and democracy. In fact, the main rivals of Iran and allies of the US are Saudi Arabia- a country even less democratic than Iran itself- and Israel, a country that while internally free and democratic is illegally occupying a foreign territory and expelling its native population in violation of international law. So the US winning this particular exchange might not necessarily mean improving or preserving the freedom of US society, but making the world a worse place, with more injustice and future grievances. See what has produced the "existential" war against Saddam.

Obama made a deal with the Iranians to stop production of weapons grade nuclear material and to destroy related infrastructure.

This also had the side-effect of strengthening the most reasonable politics within Iran.

But no, I guess this new course undermined the career of too many apparatchiks so the Orange Man was persuaded to kick the table up in the air.

And we’re back to square one, with the loudest monkeys showing their teeth at each other...

You really believe there is a threat of Iran occupying the US and it's the reason for the US policy towards Iran?

Gosh, it's scary that people like you vote to choose the government controlling by far the most powerful military in the world.
