The fleet serving Iran and Russia does not use transponders. It's a large fleet. Ships without transponders are just a fact of life in shipping.

Sure, but for the purpose of this discussion, those ships don't matter. What matters is what the ships NOT belonging to Iran's friends do.

Technically all ships crossing the strait matter as their cargos end up being bought, sanctioned or not, Iran-friendly or not; they wouldn't have crossed otherwise. If we're talking about avoiding a global recession and worst case famine in some parts of the world, the oil and gas must start moving regardless of who is the shipowner.
