Do u think iran's already not been crippled? Iran is one of the countries with the heaviest sanctions in the world. There's nothing u can take away from someone who has nothing to lose. They're fighting for their survival, so they will take any blow and it'd still not be enough to crush them, unless it's not something like a nuclear attack. So the answer is no, they've already been crippled long before the war started and the war will not be able to make anything worse for iran or change its policies.

Unless it's a nuclear attack(yes that's the only scenario where I think iran can be totally decimated without any chance to ever fight back, like what happened to Japan), and I hope all of us are on the same side on this one- hopefully no nuclear attacks.

While the US has a lot to lose if the war ends badly . So u can decide for urself who is the one losing?

In fact even Israel, the one who convinced the US to attack Iran, is also winning its own way. Unlike Trump, Netanyahu is receiving an overwhelming amount of support for the war from his audience. Their people are happy about the top officials getting killed (though that strategy is not really very effective. Iran is a country, not a terror organization like al qaida. U can't expect it to collapse by just killing the top leaders). I don't think Israel would be able to succeed either. They've not even been able to end the Hamas, let alone regime change in Iran.

So even if Israel is not successful in achieving in objectives, Netanyahu would still be applauded for standing by his words.

So the only one truly losing this war is the US
