You're not thinking ahead. If Trump really does start bombing again the only options left are the life sustaining infrastructure. Roads, bridges, power, and their oil production. This would be irrevocable for the people of Iran.

Whereas keeping the blockade in place along with Iran keeping it closed on their end results in a long term winning strategy for Trump. A lot of foreign nations depend on the strait for the oil. The longer it's closed the more they'll want it open and at the end of the day Iran is in a weaker bargaining position.

Like it or not it is driving business to the Western hemisphere. It also is directly impacting the long term outlook on Asian manufacturing. Which will force businesses beholden to investors to start eye balling production lines elsewhere.

As far as keeping the domestic front stable he can slap an export tariff on oil if need be to help reign in prices or an outright export ban. Or he can use this as an impetus to increase domestic production.

Is Trump smart enough for this? Maybe he's been in the real estate business his whole life. But in all honesty it's probably the people behind and underneath him looking at the long term issues. Out of the entire world the United States is least effected by the strait of Hormuz closure. And the world's intransigence in getting it reopened is telling in an of itself.

Iran has weaponized what is international waters effecting pretty much everyone more then their opponents. At the same time their demanding ransom for the oil on the boats these people have paid for. Hard to say you want their support against your opponent when your extorting them.

What the current situation will do is create an untenable timeline of increasing scarcity in Iran. Eventually the people will rise up against the government as history shows. But history also shows what tend to replace what existed before is seldom better.
