I can't see what incentive the Iranians have at this point to stop fighting, absent lots of boots on the ground. With every strike by the US and Israel, there is less and less for Iran to lose.

They only need to maintain a modest capability to threaten the Strait of Hormuz, as well as the water desalination plants and the oil and gas infrastructure of neighboring countries. The Iranians have a decentralized military; cutting off the head of the snake just makes them more difficult to deal with.

Iran still hasn't deployed their cyber warfare capabilities or the Houthis. I assume they have cells in many Western countries too; it won't take much to inflict significant pain on soft targets.

There is a reason this has never been attempted before.
