Completely blocking the strait will financially ruin Iran in no time at all. Almost everything they import/export goes through the strait . In 13 days their storage capacity for oil will fill up. They will have nowhere to put oil they pump. Therefore they must stop pumping oil. When oil wells stop, it ruins the oil field.

Understanding the Hormuz blockade.
These numbers are devastating for Iran.

10/10 BOTTOM LINE: A naval blockade imposes ~$435M/day in combined economic damage. Storage fills in 13 days, forcing well shut-ins that cause permanent reservoir damage. The rial enters terminal collapse. Iran's alternatives outside the Strait can replace less than 10% of Gulf throughput. The blockade makes continued resistance economically impossible.

Trump couldn't play 3-D tiddlywinks.
