The United States has warned that it could resume military strikes against Iran if ongoing nuclear negotiations fail to produce an agreement, raising concerns about a possible escalation in one of the world’s most sensitive geopolitical disputes.
Speaking at the annual Shangri-La Dialogue security summit in Singapore, US Defence Secretary Pete Hegseth said Washington maintains the capability and readiness to launch operations if diplomatic efforts break down. He emphasized that US military stockpiles remain strong and that the country is fully prepared to respond if negotiations with Tehran do not succeed.
The warning comes as American and Iranian negotiators continue discussions aimed at resolving major disagreements over Iran’s nuclear programme. The talks are focused on preventing further regional instability while addressing long-standing US concerns regarding Tehran’s nuclear activities.
Hegseth also rejected suggestions that tensions with Iran have distracted Washington from its strategic priorities in the Asia-Pacific region. He stated that the United States is increasing weapons production and expanding military readiness to support its commitments across multiple regions simultaneously.
Meanwhile, maritime security concerns have intensified after the US Navy’s Central Command issued a warning to commercial shipping operators regarding the Strait of Hormuz. The advisory described the threat environment as critical and urged vessels to exercise extreme caution while transiting through the strategically important waterway.
According to the advisory, ships operating in the area should remain in close contact with US naval authorities and follow strict navigational guidance. The notice further warned that vessels suspected of engaging in mine-laying activities could face defensive action from US forces.
Separately, the White House reaffirmed that President Donald Trump will only support an agreement that serves US national interests and prevents Iran from developing nuclear weapons. Administration officials stressed that any final deal must satisfy stringent conditions established by the president.
A senior White House official said recent high-level discussions reinforced Washington’s position that Iran must accept meaningful nuclear restrictions. Officials also noted that negotiations include measures designed to ensure the security of international shipping and maintain safe commercial access through the Strait of Hormuz.
The latest developments underscore the high stakes surrounding the negotiations, as failure to reach an agreement could increase military tensions in the Middle East and create uncertainty for global energy markets that depend heavily on uninterrupted shipping through the Gulf region.
