WASHINGTON — U.S. President Donald Trump on August 18 declared the Strait of Hormuz as 'new U.S. territory' in a Truth Social post, escalating tensions amid the ongoing six-month conflict with Iran. The announcement followed the expiration of a June memorandum of understanding (MoU) intended to reopen the waterway and facilitate broader negotiations.
Trump’s declaration came as Iran reiterated its refusal to reopen the strait, which handles one-fifth of global oil shipments, until U.S. demands are met. The White House confirmed that no talks with Iran are currently scheduled, contradicting earlier statements by Trump’s envoy, Jared Kushner, who had suggested progress in negotiations.
Immediate Developments: Trump’s Declaration and Iran’s Response
On August 18, Trump posted a map on Truth Social labeling the Strait of Hormuz as 'NEW U.S. TERRITORY', accompanied by a blue circle around the waterway. The post followed his earlier remarks in the Oval Office, where he called the idea 'an excellent idea' and stated that the U.S. already controls the strait through its naval blockade.
Iranian officials swiftly condemned the declaration. Mohammad Bagher Ghalibaf, speaker of Iran’s parliament and chief negotiator, stated that the strait 'will not be opened until the American commitments stipulated in the MoU are implemented.' These demands include:
- The removal of the U.S. naval blockade
- The lifting of oil sanctions
- The unfreezing of Iranian assets
- An end to all military operations in the region
Kazem Gharibabadi, Iran’s deputy foreign minister, reposted Trump’s map with a warning: 'Soon his delusion regarding the Strait of Hormuz will either be corrected or we will correct the delusions of this deluded man.'
Collapse of Negotiations and Escalating Tensions
The June MoU, which aimed to halt hostilities and reopen the strait, expired on August 17 without a finalized agreement. Trump stated on August 18 that 'there are no talks or conversations going on, or scheduled, with the Islamic Republic of Iran.' He added that the U.S. naval blockade remains in full force and claimed that 'all water mines have been removed or detonated.'
Iran, however, disputed Trump’s claims. Esmail Baghaei, an Iranian foreign ministry spokesperson, stated that Iran and Oman had reached an 'understanding regarding the map of the transit route' through the strait, but noted that U.S. approval is required for implementation.
Shipping data showed minimal vessel crossings through the strait on August 17, with reports of a vessel struck by an unknown projectile in the waterway, causing engine damage and a crew casualty. The UK Maritime Trade Operations confirmed assistance from the Omani Coast Guard.
Broader Context: War, Blockades, and Regional Impact
The conflict between the U.S. and Iran began on February 28 following a U.S.-Israeli attack on Iran, triggering a broader regional war. Since then, Iran has maintained control over the Strait of Hormuz, requiring vessels to seek permission and pay transit fees. Trump has framed the naval blockade as effective, citing a reduction in oil shipments and lower oil prices as evidence of success.
Trump’s declaration risks further inflaming tensions, with Iranian officials accusing the U.S. of reneging on commitments under the MoU. Ghalibaf accused U.S. negotiators of being 'out of their depth and unserious,' while Iranian Foreign Minister Hossein Amir-Abdollahian stated that the strait 'will remain closed until the U.S. meets Iran’s demands.'
Regional allies have also weighed in. Qatari Foreign Ministry spokesperson Dr. Majed al Ansari noted that mediators were awaiting a bilateral agreement between Oman and Iran before resuming broader U.S.-Iran talks.
Economic and Political Fallout
The collapse of negotiations and continued closure of the strait have driven up oil prices and sapped investor confidence, with stock markets sagging and borrowing costs rising for major economies. Trump has dismissed concerns, stating that the U.S. is 'taking out millions of barrels of oil a week' and that oil prices will continue to decline unless the U.S. takes 'much more drastic action.'
Anti-war sentiment is rising in the U.S., with Trump facing pressure on Capitol Hill over the unpopularity and cost of the conflict. Voters in Florida, Alaska, and Wyoming will head to the polls in upcoming elections, with the war’s trajectory a key issue.
What’s Next?
The Strait of Hormuz remains a flashpoint, with both sides dug into their positions. Iran has rejected any reopening of the strait until its demands are met, while the U.S. has doubled down on its blockade and territorial claims. The absence of scheduled talks suggests that direct negotiations are unlikely in the near term, raising the risk of further escalation.
Shipping routes through the strait remain high-risk, with Iranian mines and drone attacks continuing to threaten vessels. The international community’s response to the crisis will likely hinge on whether regional mediators can broker a compromise or if the conflict spirals into a broader confrontation.
