I wouldn't be surprised if there's ground troops to secure Straits of Hormuz. But we're not full-on invading Iran.
Put yourself in their shoes and consider that you don't like your government much and your country has been attacked by someone unserious and not trustworthy with open interests of taking away the resources of your country together with a nation that recently exterminated 100K people who are mostly civilians and their leader is due for trail for war crimes and genocide. In the case of their victory, do you consider what follows really will be a better deal than what you got with your government? I don't think that the majority will say yes to this. Iran isn't going to give, they will take the pounding until the attackers can't do it anymore. It's huge country(as much as France, Germany and Spain combined) with 90M people, they can take a lot of pounding.
Put yourself in Israel's shoes, you have great ambitions and you don't hold yourself from waging wars and killing however many people you like, the population doesn't punish you and you do all that on someone else's dime. Would you hold back? I don't think so, Israel isn't going to give.
Put yourself in US shoes, for some reason you are fully invested in Israel's ambitions, you are powerful and rich and the population doesn't really punish you for wars no matter the outcomes. The elections are years away, you can enrich yourself and people around you with betting on markets with insider information, you can profit from this in so many ways and if you want to feel good about yourself you can expose yourself only to people who like you no matter what you do and if you stop now you will be a loser and it wouldn't change what people say to you and my reduce your importance. So no, I don't think that US, specifically trump will give.
If no one is giving, the only way forward is escalation. Troops on the ground, nuclear attacks, attempt of genocide through starvation, chemical attacks - I think everything is on the table.
From what I read, it seems like USA will attempt and maybe take with ground operation some island on the Iran shores that is apparently very important infrastructure. Do you think that Iranians will be like "oh no, the buffoon and the genocidals took over our highly lucrative pipeline terminal, maybe we should give the rest of our resources to them and let them govern us"? I don't think so, which means later there will be large scale ground operation - unless someone stops Trump or Netanyahu.
PS: You might not agree with the "unserious and not trustworthy buffoon" and the genocide phrases but most of the world agree, especially in Europe. Only in Hungary and Romania the US and Trump image is in the net positive. Check out the numbers.
(Also I'd be highly surprised if they haven't run the numbers and calculated scores for which specific units contain the most non-citizens, new citizens, and other untermensch)
