I'll just go ahead an be blunt then. This is going to end either with the US breaking Iran's will to fight or vice-versa. How that is accomplished is open for debate. Will it go nuclear? Doubtful. Could it go nuclear? There is always that possibility then again, Putin has been threatening such action for how long now?
This tit for tat approach is not going to end the conflict.
In spite of what the wishers and hopers on both sides believe, neither side is fully in control of the Strait. That is fact and not worth the debate. If you choose to disagree, feel free to follow your preferred PowerPoint postings on Twitter in order to feel better.
