They're getting absolutely wrecked, but it doesn't mean it's good for the US. This is basically warfare 101, you can have a undisputed tactical victory and a complete strategic failure at the exact same time, in that case the tactical victory is bombing a country which is like 20 years behind in technology and spend 10% as much as the US on defense (wow good job!), the strategical blunder is that it did not achieve anything good for the short nor long term for anyone involved, if anything it helped Russia and China which kept being mentioned as the US arch enemies
Iranians don't like their current government much but they don't particularly like getting fucked up by Israel and the US either, especially when you kill 170 kids on day 1 and then lie about it on live tv. How did it go in Syria, Libya, Afghanistan, Iraq? Yeah, not so good. It's always about "preventing wars" and "bringing freedom", but it ends up being "bringing wars" and "consolidating authoritarian regimes"
Time will tell.
