President Donald Trump said Monday that his administration is working toward a new nuclear agreement with Iran that he claims would significantly improve upon the 2015 Obama-era deal, framing the effort as a major national security priority.

In posts on Truth Social, Trump criticized the Joint Comprehensive Plan of Action, calling it insufficient and arguing it failed to prevent Iran’s long-term nuclear ambitions. He said any agreement reached under his administration would be designed to ensure Iran never obtains a nuclear weapon and would provide broader regional and global security.

Trump contrasted his approach with past negotiations, saying the current effort would rely on a combination of diplomatic pressure, economic leverage, and military deterrence. He argued that this strategy would produce a stronger and more durable outcome than previous agreements.

The president also used the posts to criticize Democrats, accusing them of attempting to weaken U.S. negotiating leverage during sensitive talks. He said political opposition was complicating efforts to reach what he described as a favorable resolution.

Negotiations with Iran remain ongoing amid heightened regional tensions, including recent unrest involving shipping routes in the Strait of Hormuz. U.S. officials have continued diplomatic preparations for additional talks, with a delegation expected to include Vice President JD Vance, envoy Steve Witkoff, and senior adviser Jared Kushner.

Iranian officials have not confirmed participation in the next round of discussions, which remain subject to ongoing diplomatic and security developments.

Trump said he is not operating under time pressure and suggested that a final agreement could be reached quickly if negotiations proceed as planned. He described the effort as a long-delayed opportunity to resolve decades of nuclear-related tensions with Tehran.

The White House has not released additional details on the status or timing of the talks.
