WASHINGTON — President Donald Trump issued a stark warning to Iran on Tuesday after the U.S. Navy reported a major milestone in efforts to secure the Strait of Hormuz, saying American forces had cleared mines from international waters in the strategically vital passage and would respond forcefully to any attempt to mine it again.
Trump said all mines in the international waters of the Strait of Hormuz had either been removed or detonated. He warned Tehran that any vessel involved in placing new mines would face what he described as immediate destruction. Reuters independently reported Trump's announcement and said he also cited U.S. Space Force monitoring of the waterway.
The development comes as the United States and Iran remain locked in a prolonged conflict, with Washington simultaneously escalating economic pressure against Tehran and attempting to maintain maritime traffic through one of the world's most important energy chokepoints.
Navy milestone changes the Hormuz standoff
The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and Arabian Sea. Its strategic importance comes from the enormous volume of energy normally transported through the waterway.
The U.S. military has been conducting a naval blockade and escort-related operations in the region while attempting to prevent Iran from restricting commercial shipping.
Fox News reported that U.S. forces had redirected 71 commercial vessels, disabled three and boarded two as part of enforcement efforts. Humanitarian vessels have been permitted to pass under separate arrangements.
The reported removal of mines represents an important operational development because mines can threaten both military and commercial vessels without requiring a conventional attack.
By declaring the international waters cleared, the Trump administration is signaling that U.S. forces believe they have regained greater control over a crucial portion of the maritime route.
Trump delivers a direct warning to Tehran
Trump's warning was aimed at preventing Iran from attempting to restore the maritime threat.
The president said the United States would not tolerate another effort to place mines in the waterway and warned that vessels responsible for doing so would be destroyed.
The warning raises the stakes for any future Iranian attempt to interfere with shipping.
A new mining operation would not simply create a navigational hazard. It could trigger another direct confrontation between U.S. and Iranian forces at a time when both sides are already engaged in a dangerous military and economic confrontation.
Reuters reported that Trump described the U.S. position as a “Zero Tolerance” policy toward new mine deployments.
Why mines are such a serious threat
Naval mines are particularly dangerous because they can remain hidden beneath the water and may not require a large military force to deploy.
A mine strike can damage or disable a commercial tanker, forcing other vessels to avoid the area even when no broader attack is underway.
That makes mining an effective way to disrupt shipping while creating uncertainty throughout global energy markets.
The United States therefore has a strong incentive to identify and remove mines before commercial traffic increases.
The operation also demonstrates the importance of mine-countermeasure capabilities. Clearing a waterway requires specialized equipment, surveillance and careful identification of potential explosive devices.
Oil shipments remain far below normal levels
Despite the U.S. military's efforts, oil traffic through Hormuz remains significantly disrupted.
Reuters reported that oil shipments had fallen from more than 20 million barrels per day before the conflict to roughly 5 million barrels per day as of Monday, based on Vortexa data.
Other estimates have produced substantially different figures.
The Wall Street Journal reported that U.S. officials claimed more than 8 million barrels per day were moving through the strait, with some days reaching 15 million barrels. Commercial tracking companies, however, estimated considerably lower volumes, generally between 2 million and 6 million barrels per day.
The discrepancy reflects the difficulty of measuring maritime oil flows during a conflict. Some tankers have turned off tracking systems, while different organizations use different time periods and methods for estimating cargo movements.
Regardless of the precise figure, shipping through Hormuz remains well below normal pre-conflict levels.
The economic battle is intensifying
The military developments came as the Trump administration launched a major new sanctions campaign against Iran.
Treasury Secretary Scott Bessent described the measures as an “Economic D-Day” effort designed to isolate Tehran financially and target networks helping Iran circumvent existing sanctions.
The Treasury Department sanctioned nearly 60 individuals, entities and vessels that Washington says form part of Iran's so-called shadow fleet, which has been used to move oil and other goods while attempting to evade sanctions.
The administration's strategy therefore combines two forms of pressure.
The first is military and maritime pressure intended to protect shipping and prevent Iran from controlling the Strait of Hormuz.
The second is financial pressure intended to reduce Iran's ability to earn revenue and maintain its economy.
Iran says it is prepared to withstand sanctions
Iranian officials have rejected the administration's characterization of the sanctions as decisive.
Iranian Economy Minister Ali Madanizadeh said Tehran had prepared for the new measures and claimed the government has a two-year plan for managing the economic pressure.
He predicted that the American campaign would ultimately fail.
Iran has faced U.S. sanctions for decades, giving its government experience in attempting to circumvent restrictions and maintain trade relationships with foreign partners.
At the same time, the latest sanctions are arriving amid an already severe economic crisis caused by the conflict and the disruption of energy exports.
Iran also faces pressure over shipping attacks
The maritime confrontation escalated further after Iranian forces attacked an oil tanker in the Strait of Hormuz, according to Fox News' live coverage.
The attack occurred only hours after the United States announced the new sanctions.
That sequence illustrates the increasingly direct connection between Washington's economic strategy and Tehran's maritime response: as the United States increases financial pressure, Iran retains the ability to threaten commercial shipping in an effort to raise the economic cost for Washington and other countries.
A separate tanker was also reported disabled after being struck by a projectile near Oman, although the crew was reported safe and no environmental damage was initially reported.
Washington keeps military force on the table
Although the administration has emphasized sanctions, U.S. officials have made clear that military action remains an option.
Defense Secretary Pete Hegseth said the administration was not ruling out kinetic strikes in or around the Strait of Hormuz.
“If Iran is foolish enough to overplay their hand,” Hegseth said, the United States would respond as necessary, while emphasizing that economic pressure is currently hurting Iran.
That warning adds significance to Trump's latest statement.
If Iran attempts to place new mines, the United States has already indicated that it could treat the action as a direct military challenge.
The global energy market is watching
The Strait of Hormuz is important far beyond the United States and Iran.
Oil-producing states around the Persian Gulf depend heavily on the waterway to reach international markets. Major Asian economies are particularly exposed because they import substantial quantities of Gulf energy.
Any prolonged disruption could therefore raise transportation costs, increase insurance premiums and put upward pressure on oil prices.
The threat is not limited to the number of barrels physically prevented from leaving the region. Even uncertainty can cause traders and shipping companies to demand higher premiums for operating in a dangerous area.
That is why the reported mine-clearing operation matters economically as well as militarily.
Diplomacy remains uncertain
Despite the escalating confrontation, diplomatic efforts have not completely disappeared.
Pakistan has been involved in mediation efforts between Washington and Tehran, with Iranian officials indicating that discussions about reopening the Strait of Hormuz remain possible.
But the two sides remain far apart.
Iran has resisted what it views as unacceptable U.S. demands, while the Trump administration has continued increasing pressure on Tehran.
The latest developments therefore present a contradictory picture: military forces are working to make the waterway safer for shipping while political tensions continue to make another confrontation possible.
What Trump's warning means
The most immediate significance of Trump's statement is deterrence.
By publicly declaring the strait cleared and warning that any new mining attempt would result in the destruction of the responsible vessels, Washington is attempting to establish a clear threshold for Iranian action.
The message is that Iran may challenge the United States politically and economically, but another attempt to close or obstruct the waterway could trigger a rapid military response.
For global energy markets, the success of the mine-clearing effort could eventually allow more commercial traffic to return.
For Iran, however, the development represents another loss of leverage over the strategic waterway.
And for the Trump administration, maintaining freedom of navigation in Hormuz has become a critical test of whether its combination of military pressure, sanctions and diplomacy can force Tehran to change course without producing an even wider regional conflict.
The Strait of Hormuz remains open to a degree, but the latest confrontation shows that its security — and the global oil supply that depends on it — remains directly tied to the next move by Washington and Tehran.
