Trump renews threat of military action against Iran, says U.S. may have to ‘give them the hammer’

Donald Trump renewed his threat to strike Iran, saying the United States may eventually have to deliver a major military blow despite ongoing diplomatic efforts. At a rally in Iowa, he said he had held back to avoid additional casualties, claimed U.S. action had destroyed Iran’s nuclear capabilities, and said fuel prices were a small price to pay for U.S. security.
