The Iranian navy was destroyed. It will be 30 years before Iran has a functioning navy again.
The Iranian air force was severely debilitated. Again, 30 years before they have a functioning air force.
Those are enormous gains for Israel, but the US gets some benefit from them to. (Israel is the huge winner here -- look at all the heavy lifting we did for them and THEN we PAY them for the privilege of doing so).
We killed thousands of Islo-Sunni Iranians, which is always good. A few Shiates too.
We destroyed their nuclear program, which is really good. It will be 7-10 years before they can get back to where they were on whatever it is they were doing.
We weren't able to achieve the goal of regime change or "secular Iran," but that was always fantastical and ridiculous fake-aspiration marketing-to-the-MAGAs sh!t to begin with.
We enacted some measure of revenge for the takeover of the US embassy, which was LONG overdue.
So there are some significant tangible benefits. But I agree, ultimately Trump and Hegsmiths fvcked it with lack of planning, unclear objectives, and ridiculous rhetoric. The ROI on the whole project is WAY in the red (- (neg) $$.00) (boondoggle). I'm just saying that there are some benefits.
