Donald Trump announced that the United States has begun what he called “major combat operations” against Iran, marking a sharp escalation in tensions between Washington and Tehran. In a social media statement, Trump said the strikes are aimed at crippling Iran’s missile capabilities, naval assets, and critical military infrastructure, describing the move as a necessary step to protect American interests.

Trump acknowledged that U.S. casualties are possible but argued the operation is essential to prevent Iran from developing nuclear weapons. He warned Iranian leadership that they face a clear choice: surrender or endure what he described as overwhelming consequences. The announcement follows weeks of failed negotiations over Iran’s nuclear program and rising diplomatic strain between the two nations.

According to reports, the campaign is being conducted in coordination with Israel. Trump also addressed the Iranian public, urging them to take control of their nation’s future once the conflict ends. Global leaders have responded with alarm, calling for restraint and warning the confrontation could destabilize the wider region.
