US Senator Lindsey Graham said Wednesday that President Donald Trump remains adamant about preventing Iran from obtaining nuclear weapons, following a recent conversation between the two, CNN revealed on Wednesday. “He’s very focused, very calm,” Graham told CNN’s Manu Raju. “I feel like when he says no nukes for Iran, he means it.” According to Graham, Trump believes Iran misjudged his willingness to act and now sees their nuclear ambition as a global threat that must be eliminated. “The sooner we end this threat, the better for mankind,” Graham added. Trump reportedly provided “no timetable” for potential military action, but made clear that diplomacy has run its course and future responses could be decisive.
