US President Donald Trump is closely monitoring Iran's reaction to ongoing demonstrations before making a final decision on the scale of any potential military action, according to a report. Advisers have cautioned that a major strike is unlikely to overthrow the current government in Iran and could escalate into a wider conflict. The report indicates that more military resources are being positioned in the Middle East to prepare for possible action and to safeguard American forces and allied countries in the region. Trump has not yet made a definitive choice on the extent of any response, as officials continue to assess the situation and its possible outcomes.
