I don't think Iran expected an attack from USA so soon, so they were caught by surprise, and the lack of innovative and immediate actions from their side right now displays that. They are only threatening USA verbally. The same goes for Russia and China, what also indicates they were caught by surprise.

Now Iran is cornered. Their attention must be focused on the physical integrity of Khamenei, who is potentially the next target of the USA and Israel. He has already indicated possible successors.

The "axis" strategy now is to threat USA (psychological agression), claiming that if Khamenei is attacked, Pandora Box is going to be opened in the world.

I believe it's just a matter of time until this conflict escalates. There is no returning point. Both sides are too hurted to talk to each other. If some kind of peace has to happen yet, it must be on the context of the "fake peace" narrated on The Bible, which won't last long.
