The United States is deploying significant military assets to the Middle East, including an aircraft carrier group and thousands of troops, as tensions rise over Iran's crackdown on protests. President Donald Trump has warned of potential military action if Iran proceeds with mass executions of detained protesters, though he recently claimed Iran halted such plans. The USS Abraham Lincoln carrier strike group is moving into the region, set to join other naval forces already present, while additional air and ground assets are being positioned to enhance readiness. The buildup comes amid ongoing unrest in Iran, where protests have led to thousands of deaths and detentions, and as Iranian officials threaten swift trials and executions for demonstrators.
