Tensions between Iran and the United States have escalated after a senior Iranian military official warned that renewed conflict is now “likely,” following Washington’s rejection of Tehran’s latest diplomatic proposal.
The warning came shortly after US President Donald Trump dismissed the Iranian plan during ongoing negotiations aimed at easing long-standing nuclear and regional security tensions. According to US officials, the proposal failed to address key concerns, particularly around missile development and Iran’s regional activities, leading to a breakdown in early diplomatic momentum.
The talks, which are being held in Islamabad, had been seen as a potential step toward reducing tensions between Iran and the United States. However, the rejection has stalled progress and intensified rhetoric on both sides.
In response, Iranian military leadership has adopted a more aggressive stance, warning that the country is prepared for confrontation if diplomatic conditions are not met. The shift marks a departure from earlier cautious optimism surrounding the negotiations.
Meanwhile, security has been significantly tightened in Islamabad, with Pakistani authorities deploying extensive protective measures for foreign delegations, including restricted airspace and heightened security zones around key venues.
Analysts say the breakdown highlights deep mistrust between the two sides, with the risk of escalation increasing if negotiations fail to regain momentum. Concerns have also grown over potential regional instability and its impact on global energy markets.
As discussions continue under heightened pressure, the international community remains alert to whether diplomacy can still prevent further deterioration.
