Again, we haven't made a concerted effort to force open the strait yet.

And we’re not likely to. Forcing open the strait almost certainly would require large numbers of ground troops. Iran is aiming to charge a toll on the strait. That means short range missiles and drones, not mines; which means land forces on the coast, not naval forces. And I just can’t see Trump willing to put boots on the ground like that. He might be willing to restart the air war if the ceasefire really falls apart, but not ground forces to seize the coastal areas to secure them against mobile missiles and drones.

He’s blowing smoke up Iran’s rear end

Perhaps, but words matter in diplomacy and international relations. The President of the United States has publicly approved Iran’s plan to charge “tolls” through suggesting we’d partner up with them. That makes it more easier for them to at least try to do it, because they have a little more cover.
