Iran hit the targets they wanted to hit. They did it without even using their best missiles. I know it’s not impressive to you unless tens of thousands of civilians are killed, but the fact Iran was able to win a decisive military victory without civilian casualties only makes it more impressive to sane people.
In my country (USA) they are openly admitting they do not have missile defense against Russian, Chinese, Iranian hypersonic missiles. House Armed Services committee 4/12 shows them throwing tens of billions of dollars to develop them and they only hope to have them by 2035.
Iran launched a lot of old missiles they knew US/Israel could intercept, and it helped them gather valuable information about how they do it. They had US/Israel chasing $200,000 drones with $80,000,000 F-16’s and $300,000,000 F-35’s. You may find that impressive, but I don’t.
