U.S. President Donald Trump on Monday described the fragile ceasefire between the United States and Iran as being on “massive life support,” warning that tensions in the Strait of Hormuz continue to threaten regional stability despite ongoing diplomatic contacts.

Speaking to reporters in the Oval Office, Trump said the truce technically remains in place but is “unbelievably weak” as both sides continue hostile actions and military posturing in the Gulf region.

“I would say the ceasefire is on massive life support,” Trump said, while accusing Iran of failing to commit seriously to negotiations aimed at ending the conflict.

The latest remarks come amid continuing disagreements over Iran’s nuclear programme and maritime security in the Strait of Hormuz, a critical global oil shipping route that has witnessed repeated military incidents in recent weeks.

Trump firmly reiterated that any future agreement with Tehran must include a complete halt to Iran’s pursuit of nuclear weapons.

“I have a very simple plan — Iran cannot have a nuclear weapon,” he said, adding that Tehran’s latest response to a U.S.-backed peace framework failed to address Washington’s central demands.

The U.S. President dismissed Iran’s counterproposal as “a stupid proposal” and “simply unacceptable,” accusing Iranian leaders of repeatedly changing their negotiating positions.

According to Trump, Iran had earlier indicated willingness to allow the removal of its stockpile of enriched uranium from underground nuclear facilities allegedly damaged during previous U.S. strikes. However, he claimed Tehran later reversed its position by omitting any such commitment from its formal response.

“They agree with us and then they take it back,” Trump said. “You make a deal, and then they send you a document that changes everything.”

Trump also alleged divisions within Iran’s leadership between moderates seeking a diplomatic settlement and hardliners advocating continued confrontation with the United States.

“The moderates are dying to make a deal,” he said. “The lunatics want to fight till the end.”

The escalating rhetoric follows continued military tensions in and around the Strait of Hormuz, where both countries have traded accusations over attacks on naval vessels, shipping disruptions, and enforcement of maritime blockades.

Despite the sharp exchange of words, diplomatic efforts involving regional mediators, including Pakistan and Qatar, are continuing behind the scenes in hopes of preventing a broader regional conflict.

Analysts say the future of the ceasefire remains uncertain as negotiations over sanctions relief, maritime access, regional security, and Iran’s nuclear programme remain deeply contested.
