WRT the Hormuz Strait, Iran closing it off 2 weeks ago would be a different story, as 2 weeks ago, Iran was viewed as a dangerous, powerful enemy with tons of ballistic missiles that could cause serious damage to whoever would challenge them militarily. Today, the story is completely different. Iran has never been weaker in both public perception, and actual military might. They wouldn't be able to close off the strait without their entire navy being destroyed in a day. Would you want to be one of the IRGC guys told to fire on a USN Carrier group? You would be receiving your own death sentence.
