Trump's legacy hinges on an issue he has no interest in paying attention to: biographer

President Donald Trump's legacy hinges on an issue he has no interest in addressing, according to one of his biographers.

Journalist Michael Wolff argued during a new episode of the "Inside Trump's Head" podcast, co-hosted by Nico Hines, the Daily Beast’s global editorial director, that Trump's war in Iran is shaping up to end a lot like the oil crisis that plagued former President Jimmy Carter long after he left office. Wolff noted that Americans have become increasingly sensitive to rising gas prices resulting from the war, similar to the crisis Carter faced when the former Iranian regime fell, he added.

At the same time, Trump has failed to pay attention to the changing nature of modern warfare, Wolff argued. Not only could that cost the U.S. a decisive victory in Iran, but it could also make Trump a footnote in history.

"So the lesson that everyone should have been learning if they paid attention to Ukraine — which Donald Trump was not doing, was not interested in doing, and rather stubbornly refused to do — is that the nature of warfare was changing," Wolff said.

Wolff added that Trump's team inside the White House has no clue how to respond to the crisis that the president has created.

"Everybody within the white House and within the Trump political team is aware that they don't know what to do about this," Wolff said. "They literally do not know what to do. They don't know how to get us out of the war, and they don't know how to manage this on a political basis."
