What legitimate reports detail their military losses? Practically every single thing the US is pushing out is pure untrustworthy propaganda on the subject. Even if those specific elements are destroyed, it doesn't mean much. Planes and boats are for forward aggression. They have primarily been wrecking havoc with missiles and drones, which they supposedly have plenty more of.
Iran is China and Russia's pivot point into the West. China isn't going to let such a massive intelligence and military asset go to waste. I'd just about guarantee they were involved in strong arming Pakistan into pushing for peace talks last week to avoid the threatened total destruction. Short of a nuke being dropped or the entire country being bombed to shreds, Iran isn't going anywhere any time soon.
