Iranian officials have announced a transition from defensive to offensive military posture, threatening action in the Strait of Hormuz if diplomatic efforts with the United States fail to produce results by a new deadline.

Diplomatic efforts to end the conflict between Iran and the United States have reached an impasse, prompting Tehran to recalibrate its military strategy. According to a senior Iranian official speaking to Reuters on Monday, Iran has decided to adopt a "fully offensive" approach, moving away from its previous defensive position due to the breakdown in peace negotiations. The official stated that Iranian entities must prepare to escalate tensions in the Strait of Hormuz and surrounding regions, with Tehran ready to conduct what it described as a "timely and precise" military attack to counter the US naval blockade should talks collapse.

The standoff centers on a memorandum of understanding signed in June that aimed to establish a 60-day negotiating period to resolve the broader conflict, which began on February 28. However, the agreement unraveled over disputes regarding control of the Strait of Hormuz. Iran contends that point 5 of the MoU grants it management rights over the waterway, a position the United States has rejected. US President Donald Trump declared the pact "over" on July 7, while Tehran has accused Washington of repeatedly violating its commitments.

Iran has set a compressed timeline for implementation, demanding that the US fulfill all agreement provisions within weeks as a precondition for continued negotiations. Iranian officials indicated that mediators would communicate this deadline to Washington and regional states. Meanwhile, rhetoric from both sides has intensified, with Trump warning of sustained high fuel prices and declaring intentions regarding American control of the Hormuz Strait, while reiterating concerns about Iranian nuclear capabilities.
