Donald Trump is being urged by Iranians to act quickly to help protesters under attack by security forces in Iran. Trump promised he would “shoot at Iran” if security forces harm protesters. But experts say the crisis is moving too fast, and the US has no ready plan. No big US military moves have happened yet. Close US allies in the Middle East, like Qatar, call for caution. US leaders are showing Trump various military and other options. The US Secretary of State, Marco Rubio, spoke with Israel’s Prime Minister Benjamin Netanyahu. Tehran is densely populated with about 12 million people, making air strikes risky because of many civilians. Last June, US and Israeli attacks killed over 1,000 Iranians, which stirred strong nationalism. Key Iranian leaders, including Supreme Leader Ayatollah Ali Khamenei, have increased security, making targeted strikes difficult. However, some Revolutionary Guards bases and police barracks in south Tehran might be attacked. Iranian opposition leaders told Washington that violent government repression is a crime against humanity. A letter signed by seven prominent Iranians, including Nobel winner Shirin Ebadi, urged Trump to recognize the scale of violence and warned, “every minute of delay will expand the dimensions of the crime against the defenceless people of Iran.” The son of the former Shah, Reza Pahlavi, who claims some influence over protests, also asked Trump to act but told protesters to stay safe and stick together. Many experts warn that US bombing might backfire. Danny Citrinowicz, a former Israeli defence analyst, questioned if limited US action would help or worsen the situation. Sanam Vakil from Chatham House said US intervention could unite Iran’s elite and close cracks in the regime. Esfandyar Batmanghelidj noted Trump’s past failures in Ukraine and Gaza reduce chances of success now. Former UK ambassador Rob Macaire said US strikes might not bring expected results and urged focus on how any political transition can happen. The Iranian government blames external enemies for the chaos and calls for unity. President Masoud Pezeshkian admitted many protesters have real grievances but called violent rioters terrorists. He accused the US of using economic pressure as a weapon and urged citizens to support the government.
