The attacks against Kharg Island were relatively limited as even the US wanted to avoid that level of escalation. The war has been painful but Iran could rebuild, if you destroyed Kharg island it would take decades to rebuild the Iranian economy, that would be a complete scorched earth point of no return.

Maybe there have been further attacks today that I missed but if true that would be an huge escalation.

My last information was that China has no problem getting oil but that was like two days ago.
