President Donald Trump has intensified pressure on Iran to negotiate a new agreement, warning that “time is running out” for Tehran to return to discussions and avert potential military action as a major United States naval force moves toward the Middle East.

In a series of statements on social media and to reporters, Mr. Trump cited the deployment of a substantial carrier strike group led by the USS Abraham Lincoln as evidence of Washington’s resolve while underscoring his preference for a negotiated outcome.

The Trump administration’s remarks come amid escalating tensions over Iran’s nuclear activities, its domestic crackdown on nationwide protests and broader regional instability.

The naval deployment — described by the president as a “massive armada” — includes guided-missile destroyers and air assets, reflecting the United States’ effort to reinforce its military posture and provide strategic options should hostilities escalate.

Mr. Trump reiterated that the force is positioned to protect US interests and deter aggression, but he stressed that Iran has an opportunity to negotiate a deal that would preclude the use of force.

Iranian officials have responded with defiant rhetoric, with Foreign Minister Abbas Araghchi warning that Tehran would respond forcefully to any attack, characterising such action as unjustified and destructive.

Iranian state media and diplomats have also reiterated Tehran’s view that it remains willing to engage in dialogue under conditions of mutual respect, though they reject what they see as coercive demands.

Within Washington, senior officials have acknowledged the complexity of the situation, with some lawmakers expressing concern that the United States lacks a detailed post-conflict plan should military action unfold.

Analysts note that the carrier strike group’s arrival near the Persian Gulf increases US military flexibility and serves both deterrent and diplomatic signalling purposes.

The posturing comes against the backdrop of months of stalled negotiations over Iran’s nuclear programme, efforts that have at times included limited talks mediated by third parties but have yet to produce a substantive agreement.

As Mr. Trump presses for a deal that he says would restrict Iran’s nuclear ambitions and enhance regional security, the United States continues to weigh the delicate balance between coercive pressure and diplomatic engagement in pursuit of a settlement.
