President Donald Trump outlined four primary objectives for the US military campaign in Iran, stating the operation was projected to last four to five weeks but could extend significantly longer. He justified the intervention, which resulted in the death of Iran's supreme leader Ayatollah Ali Khamenei, by citing Tehran's nuclear development and ballistic missile program as a "colossal threat" to America and its overseas forces. Trump also claimed Iran would soon possess missiles capable of reaching the US, a assertion disputed by national security experts. The president further asserted that other nations supported US efforts against Iran's nuclear ambitions but lacked the courage to voice it. He also criticized the Iran nuclear deal brokered by former President Barack Obama, calling it a "horrible, dangerous document." Trump's remarks were made during a Medal of Honor ceremony, where he also discussed his plans for a new White House ballroom, a move that drew criticism for its perceived insensitivity.
