WTF is the plan?

Does anyone know what Trump is planning with his blockage of the Strait of Hormuz? Is there any exit plan here other than starve Iran of oil money?
Does he think they will just say "OK Mr. Trump Sir, you can have all the money and all the oil and everything because you are so amazing"?
The strait was already closed, so his plan is to close it? Does that make any kind of sense?
