The world grappled Sunday with the enormous implications after the United States inserted itself into Israel's war against Iran with an attack that raised urgent questions about what remained of Tehran’s nuclear program.

Iran threatens US bases after massive airstrikes targeting nuclear facilities. Trump claims "spectacular success," but damage unclear. IAEA confirms visible craters at Fordow. Fears grow of uncontrolled regional escalation as casualties mount on both sides.

Vice President JD Vance said on Sunday the U.S. was not at war with Iran but at war with its nuclear program, adding the program had been pushed back by a very long time due to American strikes ordered by President Donald Trump.
