Iran’s top leadership, including President Masoud Pezeshkian and Foreign Minister Abbas Araghchi, stepped onto the streets of Tehran on Tuesday, joining thousands of residents in marking the eve of Islamic Republic Day in a show of defiance amid escalating conflict in West Asia.The public appearance, where senior leaders were seen interacting with people and participating in pro-government rallies, comes at a time when Iran faces sustained military pressure and rising regional tensions.The turnout is being viewed as an attempt by Tehran to project unity and resilience, even as the conflict with the United States and its ally Israel intensifies. In recent weeks, Iranian officials have repeatedly called for public mobilisation, framing it as a demonstration of national resolve against external threats.Simultaneously, Tehran hardened its stance against Washington, warning that American-linked assets in the Gulf region could come under attack if hostilities continue.Iranian officials have indicated that any country or entity facilitating US military operations could be treated as a legitimate target, expanding the scope of the conflict beyond traditional military installations.This raises concerns for a wide range of US corporate interests in the region, including Indian-origin Sundar Pichai-headed Google, alongside energy and logistics companies with a footprint in Gulf states.While President Pezeshkian has at times signalled a willingness to ease tensions with neighbouring countries, Iran’s broader security establishment has maintained a more aggressive posture.The dual messaging — public outreach at home and threats abroad — highlights Tehran’s strategy of combining domestic mobilisation with external pressure.Experts say the leadership’s presence on the streets is aimed at reinforcing legitimacy and maintaining morale, particularly as economic and military pressures mount.At the same time, warnings targeting US companies and interests underscore Iran’s intent to raise the costs of continued confrontation.
