Escalating US-Iran tensions in Strait of Hormuz
Bill Hemm provides a detailed overview of the escalating tensions between the U.S. and Iran in the Strait of Hormuz.
Iran warned Thursday that any commercial vessel failing to follow routes approved by Tehran through the Strait of Hormuz would face a "forceful response," the clearest indication yet that the Islamic Republic intends to assert greater control over one of the world's busiest shipping lanes.
"Any failure to comply, deviation from the designated route, or disregard for the navigation protocols of the Islamic Republic of Iran in the Strait of Hormuz will be met with an immediate and forceful response from the armed forces, endangering the security of the violating vessels," Iran's military command said in a statement to Iranian state media.
"Any disruptive action in the Strait of Hormuz will be considered a threat to Iran’s national sovereignty and will be met with a rapid and decisive action," the warning stated.
The threat comes as the United States and regional partners work to shift more commercial traffic toward a southern shipping corridor hugging Oman's coastline — an alternative route designed to move vessels farther from Iran's immediate reach and weaken one of Tehran's greatest strategic advantages.
Former military commanders told Fox News Digital the timing is no coincidence.
"The southern route creates a route they can't toll or control," retired Navy Rear Adm. Mark Montgomery said. "They felt it necessary to attack it."
SHIPPING GIANT WARNS STRAIT OF HORMUZ CHAOS IS 'NEW NORMAL' AS TEHRAN SHIFTS 4M BARRELS
Under the memorandum of understanding reached after the ceasefire, Iran agreed to use its "best efforts" to ensure safe, toll-free commercial passage through the Strait of Hormuz for 60 days while the two sides negotiate a broader agreement over the waterway's future administration.
For decades, Iran's ability to threaten shipping through the Strait of Hormuz has given it influence well beyond its borders. But that advantage is increasingly under pressure as Gulf states invest in pipelines that bypass Hormuz and the United States and Oman expand use of the southern corridor.
Nearly half of inbound commercial traffic through the Strait is already using the Omani route, according to maritime intelligence firm Windward. New data from maritime analytics firm Kpler also showed overall traffic rebounding after U.S.–Iran strikes briefly disrupted shipping, with 45 vessel crossings recorded Wednesday, up from 34 the previous day. Of those, 21 transited via the Omani route, compared with 11 using the Iranian route.
After Iran attacked vessels using the corridor, the U.S. responded with strikes on Iranian military targets tied to maritime operations. Iran retaliated with attacks on U.S. facilities and regional partners before President Donald Trump announced both sides had agreed to halt further strikes and pursue negotiations. But even as talks resumed in Doha this week, Iran continued to insist it has the authority to regulate traffic through the Strait of Hormuz, underscoring how far apart the two sides remain.
U.S. Central Command (CENTCOM) released a statement Wednesday about meeting with military leaders from throughout the Middle East, where they "underscored their shared commitment to the free flow of commerce through the Strait of Hormuz."
"Hormuz is defined under Iran’s command, not CENTCOM," Iranian Deputy Foreign Minister Kazem Gharibabadi said in a post on X. "A military summit in Bahrain cannot establish legal order and security for the Persian Gulf."
"The Strait of Hormuz is open and ships are transiting at higher levels," a senior administration official told Fox News Digital Thursday. "President Trump has been clear that Iran cannot toll the Strait of Hormuz, which is an international waterway, and active conversations at high levels continue on all aspects of the MOU."
CENTCOM could not immediately be reached for a response.

Former Navy Fifth Fleet commander, Vice Adm. Kevin Donegan, said Iran's objective isn't necessarily to halt shipping altogether.
"The IRGC has been trying to make it commercially unworkable," Donegan told Fox News Digital, referring to the Islamic Revolutionary Guard Corps. "These attacks on shipping to me aren't random. They're strategy."
Rather than closing the strait outright, Donegan said, Iran only needs to keep insurance premiums high enough that commercial shipping companies remain reluctant to return.
"Their strategy is to enforce their control of the straits," he said, by driving up insurance costs while continuing to "test the U.S. resolve."

The question now is whether Iran can translate that military pressure into lasting influence over the strait.
Under the memorandum of understanding negotiated after the ceasefire, Iran, Oman and the Gulf littoral states are expected to negotiate the strait's "future administration and maritime services" while commercial traffic moves toll-free for 60 days.
Trump has insisted on social media that there will be "NO TOLLS" after the negotiating period expires, even though the memorandum itself does not explicitly guarantee that outcome. Asked about the discrepancy, Trump argued that "common sense" and the threat of renewed U.S. military action would keep Iran from interfering with commercial traffic.
Iran, however, has signaled a different vision. An IRGC-linked news outlet portrayed last-minute revisions to the agreement — including language governing the strait's future administration and the temporary toll provision — as negotiating victories for Tehran.
America's Gulf partners have made equally clear they are not interested in rewriting the status quo.
"The management of the strait was working fine before the conflict," Saudi Foreign Minister Prince Faisal bin Farhan said. "Why should we now, as a result of a conflict, accept some novel arrangement?"
The disagreement reflects competing visions of what Iran's role in the strait looks like once the fighting ends.
Former Assistant Secretary of State David Schenker said the negotiations reflect Iran's effort to emerge from the conflict with "a new status quo in the Persian Gulf."
But preserving leverage over the strait is about more than commercial shipping.

"Iran is trying to basically step into that void," said Clionadh Raleigh, executive director of the Armed Conflict Location & Event Data project.
Raleigh argued the conflict has left Gulf governments questioning whether "the U.S. is a partner that's unreliable," creating an opportunity for Tehran to argue that Gulf security should increasingly be managed by countries in the region rather than by Washington.
Those doubts are already reshaping regional strategy.
"They're seeking to really develop their own defense posture," Raleigh said. "And they're also seeking alternative means for them to continue trade."
Those efforts have been underway for years, but the latest conflict has accelerated them.
Saudi Arabia has invested heavily in the East-West Pipeline linking Gulf oil fields to the Red Sea, while the United Arab Emirates has expanded export capacity through Fujairah, allowing crude exports to bypass Hormuz altogether.

Every barrel that leaves the Gulf without transiting the strait — and every ship that safely uses the southern corridor — chips away at the leverage Iran has historically derived from one of the world's most important maritime choke points.
If those alternatives continue to expand, Iran's ability to wield the strait as a strategic pressure point could gradually diminish even if Hormuz itself remains one of the world's most vital energy corridors.
