Trump Weighs Winding Down Iran War as U.S. Eases Some Iran Oil Sanctions and Deploys More Marines While Strait of Hormuz Remains Largely Closed
President Trump has said he is “considering winding down” U.S. military operations even as the Treasury temporarily waived enforcement on some Iranian oil shipments through April 19 to blunt energy shocks; at the same time the Pentagon has escalated strikes (including on Kharg Island), employed A‑10s and Apache helicopters, and is routing roughly 2,200–2,500 Marines on multiple amphibious warships toward the Gulf with options that include further strikes or a possible seizure of Kharg. Despite U.S. pressure and a six‑country political statement supporting preparatory planning to reopen the Strait of Hormuz, the strait remains largely closed with thousands of vessels stranded, allied governments have mostly declined to commit ships or minesweepers, and limited U.S. mine‑countermeasure capacity complicates efforts to restore commercial traffic.
📌 Key Facts
- Six U.S. Western allies issued a joint statement March 19 backing 'preparatory planning' for a potential coalition to reopen the Strait of Hormuz but stopped short of committing ships or other forces; the push was led politically by NATO Secretary‑General Marc Rutte and U.K. Prime Minister Keir Starmer, France initially resisted but acquiesced to a declaration, Japan joined at the last minute, and the U.K. has sent officers to CENTCOM — yet France, Germany, Italy and Japan have previously ruled out sending warships and it is unclear if that will change.
- U.S. and allied forces have launched a multistage air and helicopter campaign to clear the strait: low‑flying attack jets and repurposed A‑10 Warthogs are targeting Iranian fast‑attack craft, Apache gunships have been used to shoot down drones and strike one‑way attack drones, and CENTCOM says 5,000‑pound bombs have been used against underground missile silos as part of efforts to degrade Iran’s anti‑shipping capabilities.
- CENTCOM and other U.S. officials say they have destroyed numerous Iranian maritime targets — including an estimated 16 mine‑laying vessels and multiple naval‑mine storage bunkers — but analysts note U.S. mine‑countermeasures (MCM) capability has atrophied and it remains unclear how many mines, if any, are actually in the strait.
- Traffic through the Strait of Hormuz has been effectively halted since early March, the Persian Gulf has become a 'parking lot' for shipping (the International Maritime Organization estimates more than 3,000 vessels are stranded), and reopening commercial transit remains dangerous and logistically fraught.
- The White House and Pentagon are weighing a high‑risk option to seize or blockade Iran’s oil island of Kharg as leverage to force reopening; U.S. airstrikes on Kharg were described as both warning shots and preparatory shaping (officials say most defenses there were destroyed while oil pipes were left intact), but retired officers warn a seizure would expose troops to heavy risk without guaranteed Iranian concessions.
- U.S. amphibious and Marine forces are being surged: multiple Marine Expeditionary Units (MEUs) — roughly 2,200 Marines each — and amphibious ships (including USS Tripoli and the USS Boxer Amphibious Ready Group) are being redirected or sent from the Pacific and California, with three additional warships carrying about 2,500 Marines scheduled to head to the Middle East next month; U.S. troop levels in the region are reported above 50,000.
- President Trump publicly said he is 'considering winding down' U.S. military operations in Iran and suggested the Strait of Hormuz 'will have to be guarded and policed' by other nations, while administration officials caution the comment does not mean an immediate end to the campaign and expect at least 'a couple of weeks' more of heavy strikes; Trump also publicly denied plans for 'boots on the ground' even as Marines are being deployed.
- To ease an oil shock, the U.S. Treasury temporarily waived enforcement of sanctions on some Iranian oil and oil products already loaded on ships through April 19, 2026 — a move Treasury estimates could quickly add about 140 million barrels to the global market.
- Regional diplomacy and logistics have been complex: the U.S. quietly asked Sri Lanka for permission to host two armed military aircraft before beginning airstrikes and was refused (Sri Lanka also declined an Iranian docking request) and is now hosting survivors from an Iranian warship torpedoed off its coast; meanwhile strikes continue inside Iran (including at Natanz) and Iran has continued missile and drone attacks on Israel and Gulf states, undercutting any notion the conflict is tapering off.

Shashank Joshi on Why the War in the Middle East Won’t End Anytime Soon
"Shashank Joshi argues the Iran‑centered Middle East war is unlikely to end soon because strikes cannot remove Iran’s strategic depth, geography and asymmetric capabilities give Tehran enduring leverage, allied constraints and economic fallout limit U.S./Israeli options, and any attempt at decisive military solutions risks costly escalation."

Trump considers "winding down" Iran war without opening Hormuz Strait
New information:
- Trump posted on Truth Social that the U.S. is 'getting very close' to meeting its objectives and is 'consider[ing] winding down' military efforts against Iran.
- In the post, Trump explicitly lists his claimed objectives — degrading Iran's missiles and industrial base, eliminating the Iranian navy and air force, preventing a nuclear weapon, and protecting U.S. allies — and asserts they are nearly met.
- Trump now says the Strait of Hormuz 'will have to be guarded and policed' by other nations that use it and that 'The United States does not' need to do so, signaling he may end the war without reopening the strait.
- A U.S. official tells Axios the post does not signal an imminent end to the war, estimating at least 'a couple of weeks' more of 'hard and continuously' conducted strikes.
- The article reports Trump is torn between concern over high oil prices and lack of allied help on Hormuz, and his reported enthusiasm for 'obliterating' Iranian capabilities, quoting him telling a confidant, 'We're hot! We're winning!'
- Axios adds that Trump recently called NATO partners 'cowards' and described NATO as 'a paper tiger' over their refusal to send ships and minesweepers to help reopen Hormuz.

US Navy lags in minesweeping, despite years of warnings and big defense budgets
New information:
- Analysts and historical internal Navy critiques show U.S. mine countermeasures (MCM) capability has been allowed to atrophy for decades, with a 2025 Center for Maritime Strategy study calling the current state of American minesweeping 'grim.'
- Vice Adm. Stan Arthur and other officers have been warning since at least the early 1990s that mine warfare was being neglected, and the Navy’s dedicated Mine Warfare Command was dismantled in 2006, described as a 'critical institutional blow.'
- CENTCOM officials, aware of the gap, estimate they have destroyed 16 Iranian mine‑laying vessels and multiple naval‑mine storage bunkers in recent strikes near the Strait of Hormuz.
- Despite Iranian threats to lay mines, U.S. officials and outside analysts say it is unclear how many, if any, mines are currently in the Strait, with some arguing Tehran would publicize mine‑laying on social media if it had already done so.
- The Navy once had robust dedicated MCM ships and helicopters during the Cold War, reflecting an institutional understanding that keeping sea lanes open was fundamental to every other mission, but that force structure has been substantially drawn down.

Experts: Reopening the Strait of Hormuz may require U.S. ground troops
New information:
- Multiple military and maritime experts tell MS NOW that achieving minimal or zero attacks on shipping in the Strait of Hormuz would likely require U.S. ground troops to seize and hold stretches of Iranian coastline if air and naval strikes prove insufficient.
- Retired Army Gen. James A. “Spider” Marks says Marines currently en route to the region are a contingency force to create a ground “buffer zone” should airstrikes not adequately suppress Iran’s ability to fire on transiting traffic.
- Jonathan Schroden of the Center for Naval Analysis distinguishes between tolerating some continued attacks on shipping — potentially manageable with extended strikes and naval escorts — and a much more demanding standard of security that would probably require putting troops ashore.
- Maritime historian Sal Mercogliano says ship captains waiting to transit the strait have not been briefed on any clear U.S. military plan, and experts warn tanker insurance costs could spike so sharply that Washington might need to guarantee compensation for any wartime damage to entice owners to sail.

Trump mulls risky Kharg Island takeover to force Iran to open strait
New information:
- Four sources tell Axios the Trump administration is actively considering occupying or blockading Iran’s Kharg Island to pressure Tehran to reopen the Strait of Hormuz.
- A source familiar with White House thinking says the notional plan is roughly a month of additional strikes to weaken Iranian forces, then seize the island and use it as leverage in negotiations.
- Three different Marine units are already en route to the region, and the White House and Pentagon are considering sending more troops.
- A senior administration official says Trump is willing to take Kharg Island or launch a coastal invasion if needed, though no decision has been made.
- Retired Rear Adm. Mark Montgomery warns that seizing Kharg could expose U.S. troops to high risk without guaranteeing Iranian concessions and suggests escorts through the strait after about two more weeks of strikes are more likely.
- The piece confirms last Friday’s massive airstrikes on dozens of targets on Kharg were both a warning shot and preparatory shaping for a possible ground operation, with officials saying they have destroyed most defenses but left oil pipes intact.

Six U.S. allies back potential Strait of Hormuz coalition
New information:
- Six U.S. Western allies released a joint statement on March 19 expressing support for a potential coalition to reopen the Strait of Hormuz but stopped short of committing naval vessels or other resources.
- The U.K. and NATO Secretary General Marc Rutte orchestrated the push for the statement, with Rutte and U.K. Prime Minister Keir Starmer persuading French President Emmanuel Macron to drop his opposition to a political declaration while deferring decisions on practical steps.
- Japan joined the statement at the last minute ahead of Prime Minister Sanae Takaichi’s White House meeting with President Trump, and the U.K. has already sent officers to CENTCOM in Tampa to begin coalition planning.
- The joint statement condemns Iran’s ‘de facto closure of the Strait of Hormuz’ and Iranian attacks on commercial vessels and infrastructure, and says the allies are ‘ready to contribute to appropriate efforts’ and start ‘preparatory planning.’
- France, Germany, Italy and Japan have all previously ruled out sending warships during the war, and it remains unclear whether signing the statement will change those positions.
