United States President Donald Trump has announced a new 25 percent tariff on all countries conducting business with Iran, escalating pressure on Tehran amid ongoing protests and a violent crackdown. The tariffs, which take effect immediately, are part of a broader strategy that includes the possibility of military action, though Trump emphasized that diplomacy remains the preferred approach. The move follows repeated warnings from Trump about Iran's handling of protesters, with the president stating that any attack on American military bases would provoke an unprecedented response. Iranian President Masoud Pezeshkian has accused the United States and Israel of attempting to destabilize Iran, while unrest continues to grip the country, resulting in hundreds of deaths and thousands of detentions.
