Pakistan Leads Mediation Push as Iran Rejects U.S. Peace Proposal Amid Rising Tensions

Diplomatic efforts to de-escalate the U.S.-Iran conflict hit a significant hurdle on March 30 as Tehran formally rejected a 15-point peace plan proposed by the Trump administration. Despite President Trump’s assertion that negotiations are proceeding "extremely well," Iran’s foreign ministry characterized the U.S. demands as "unrealistic." Simultaneously, the conflict expanded geographically as Houthi rebels fired a missile at Israel for the first time, shortly after additional U.S. Marines were deployed to the area. Amid the escalating military rhetoric—including threats from Iran’s Parliamentary Speaker against U.S. ground troops—Pakistan has emerged as a central mediator. On March 29, Islamabad hosted leaders from Egypt, Saudi Arabia, and Turkey to discuss the security of the Strait of Hormuz and offered to host direct talks between Washington and Tehran. However, no date has been set for such a meeting, and the U.S. administration is reportedly still weighing military options, including the seizure of Kharg Island. The regional instability is also raising global security concerns. A recent analysis by Chatham House warns that the conflict, paired with the recent expiration of the New START treaty and shifting U.S. military assets from South Korea to the Middle East, is triggering a new wave of nuclear proliferation. Within Iran, prominent figures, including Supreme Leader Mojtaba Khamenei, have suggested withdrawing from the Non-Proliferation Treaty (NPT) to pursue a nuclear deterrent.
