Donald Trump dismissed Iran’s decision to withdraw from the US-Iran memorandum of understanding (MoU), saying he “couldn’t care less” about Tehran’s move. Speaking during a brief telephone interview, Trump said his administration’s priority remains preventing Iran from developing a nuclear weapon. His remarks came as tensions between Washington and Tehran continued to rise despite last month’s agreement.

Trump said Iran’s withdrawal would not change the United States’ overall objective. He repeated that ensuring Iran “never has a nuclear weapon” remains a key national security goal. Meanwhile, US officials said diplomatic channels remain open if Tehran decides to return to negotiations. They also defended Washington’s current approach to the crisis.

The MoU was signed in mid-June to reduce hostilities after months of conflict involving the United States and Israel. The agreement included steps to lower military tensions, ease some sanctions and create a framework for future technical negotiations. However, both sides now accuse each other of violating important commitments under the deal.

Disputes over the Strait of Hormuz have further strained relations between the two countries. Both sides have exchanged strikes and increased military activity around the strategic waterway. The route handles a significant share of global oil shipments, making the latest escalation a growing international concern.

Iranian officials argue that Washington failed to fulfil its commitments under the agreement. In contrast, the Trump administration accuses Tehran of taking provocative actions and refusing to support efforts aimed at reducing tensions. As a result, the agreement has come under severe pressure.

The worsening conflict has also increased political pressure on Trump at home. Recent American military casualties have drawn criticism from lawmakers and voters. During the 2024 presidential campaign, Trump repeatedly promised to avoid prolonged military conflicts in the Middle East.

Despite the criticism, Trump has defended his administration’s handling of the crisis. He insisted that preventing Iran from obtaining nuclear weapons remains a top national security objective. Finally, US officials said diplomacy remains possible if Tehran is willing to resume meaningful negotiations, although the future of the agreement remains uncertain.
