The short article from Jin10 still isn't comprehensive enough, missing a key piece of information,

According to Reuters' report, Trump's stance on controlling the Strait of Hormuz is not just about Iran's dissatisfaction, but also points the finger at Oman.
Why is Trump criticizing Middle Eastern allies? This is a recent "positive strategy" by Iran that has played a role!
Previously, Iran stated it would not charge tolls for passing through the Strait of Hormuz, while also proposing that the rights to the strait belong to the coastal countries,
Iran is trying to tell Gulf states with this attitude: everyone earns money together, and the benefits of the strait are shared; I won't monopolize it.
Iran's outreach means that once Gulf countries recognize this shared "cake," they might oppose the U.S., which would weaken America's dominance and control in the Middle East,
And this is something Trump or the U.S. would never allow.
Therefore, tonight's speech by Trump is not only a warning to Iran but also a warning to others, because Oman and Iran are key positions guarding the strait.
Warning Oman now is essentially telling all Gulf nations that the strait isn't controlled by Iran, nor can Gulf countries control it;
Control must be in the hands of the U.S.
Why is Iran's move considered a positive strategy? Because the U.S. doesn't manage it, and the Middle East is gradually forming a common interest, weakening U.S. control.
If the U.S. intervenes, it will naturally cause dissatisfaction among Gulf countries, just like Oman now.
In name, Oman won't say much, but seeds of dissatisfaction with the U.S. have already been planted, and these seeds are likely to gradually spread among Gulf states.
Looking at the bigger picture, this U.S.-Iran conflict, in terms of U.S. control in the Middle East and the authority among allies, has already entered a phase of failure!
Of course, these effects are hard to see in the short term; the seeds of doubt need time to develop and spread, and the effects will be long-lasting and persistent!
