Just very unlikely in this case. TFA explains its case and why yours is very unlikely; while you're just repeating your opinion based on faith ("once again"), with no analysis and no demonstrable knowledge of the specifics.

TFA explains why this isn't feasible without massive loss of life and dollars spent, and furthermore, it also explains why keeping the Strait open and low risk is unfeasible without boots on the ground (not just strikes from the skies), which, in turn, would be very costly for the US in Iran. I mean, all of this is addressed in the article.
