President Donald Trump says the United States may need to strike Iran “even harder,” but he will wait to see whether negotiations produce a deal. Speaking at a commencement address at the U.S. Coast Guard Academy in New London, Connecticut, Trump repeated a stance framed as “either/or.” He said, “We hit them very hard. We may have to hit them even harder - but maybe not,” and added, “We’ll see what happens.” Trump also stated that the U.S. will not allow Iran to obtain a nuclear weapon, calling it “very simple.” He said he believes much of Iran’s military capability has been degraded, describing its navy and air force as “gone,” and characterized the key question as whether the U.S. carries out further military action or whether Iran signs an agreement. Reuters reporting cited in multiple outlets notes that Trump said earlier on Wednesday that negotiations are in the final stages and warned of additional attacks unless Iran agrees to a nuclear deal.
