On the contrary, Iran's exports are now zero.
US is doing business as usual. Its massive east coast / west coast and life in general in US is normal as if nothing is happening (like a war at other side of world). Infact US exports are now at highest levels when GCC is producing a fraction. Only KSA & UAE are able to export via pipelines but at lower capacity then normal. Oman is already out of strait. Only countries which are most suffering due to blockade are Iran, Kuwait, Qatar, bahrain and countries like india, pakistan and others for higher fuel prices.
As far as destruction over Iran and Iran's retaliation is concerned. We have to understand that Iran's retaliation is against GCC and not to US mainland or not even against US navy. None of US navy warships are destroyed. Iran's way of doing damage is that okay if US destroy Iran's refinery, Iran says okay now I will destroy Qatar's refinery lol. In a way to pressure US that we will inflict damage to a third country since we can't damage you.
The difference at military level was so obvious when US helicopters and a tanker aircraft was seen flying over Iran and they rescued two of their pilots from Iran's own territory.
I agree and always stated that Iran is ABSOLUTELY GREAT at building lots of lots medium range missiles and lots of underground missile bases. Also it has a great stamina to take punishment but at same time keep fighting which is absolutely brilliant. But that does not give Iran an edge over US. US got world's largest economy, so many commands, thousands of fighter jets, over 500 refueler tankers, every asset is numerous spread across several commands over the world. it has used a fraction of its military might in this operation. US can bring more and more if ever required. So saying that US is finished or it at mercy of Iran and things like that are just pure exaggerations.
