Biggest problem for Iran, is I do not see how they can hope to contest, let alone reestablish control of their own airspace

All their airforce and serious air defence was seemingly destroyed or negated in the opening strikes

Hence Israel has air superiority and freedom of action over Iran

Not a single Israeli aircraft beyond a drone, has been successfully shot down over Iran yet with any form of confirmation

And there are still Mossad and special forces teams operating on the ground in Iran

Iranian response is limited to the, while spectacular, ultimately, so far rather limited in destruction, ballistic missile volleys on Israel, which I question the long term sustainability of conducting.

Meanwhile Israel is seriously degrading the official Iranian military now, after the IRGC elements were already extremely degraded in the first attacks, and Israel is now moving on to the main economic infastructure of the Iranian state

Plus, the fact that Iran is full of traitors and Israeli assets who seem more than happy to sell out their own side and give targets of senior Iranian officials and assets to Israel

Not writing them off yet, but the state of play is extremely against Irans favour in this
