President Donald Trump has been yelling at his White House staffers as he deals with a lingering frustration, an author revealed.In a recent episode of Inside Trump's Head, Trump biographer Michael Wolff explained to co-host Joanna Coles why the president has resorted to "yelling at people" to resolve his frustrations with the war in Iran. Trump's recent yelling about the Iran war has been reported in The Wall Street Journal and NBC News."He's stuck, he's stuck, he's stuck. He can't do anything," Wolff said. "He can retreat. He can admit defeat, which also he doesn't want to do. So he's yelling at people, 'Solve the problem! There must be something we can do.'"According to reports by the Journal and NBC News, Trump started shouting expletives and yelling at a meeting with his top national security officials over frustrations with the Iran war."He has been told over and over again — because there's effectively nothing left to tell him — that we have exhausted all military solutions," Wolff said. "We are running out of missiles. We will run out of missiles if we keep up the pace. We have done everything that an air campaign can do. There's nowhere to go. There is nothing more we can do except invade."Wolff framed Trump's 2024 campaign posture as Trump touting himself as "The 'No Forever Wars' president," which complicates his option of getting deeper into the war in Iran. However, "if he retreats, and even if he claims victory and says it's all marvelous, the Iranians still control now the Strait of Hormuz," Coles said."Trump is the Hormuz president," he concluded.
