“Most Powerful Person EVER” Piers Morgan Debates American Empire With Historians
"I feel like post World War II, the United States had the opportunity to do so many good things and then regularly chose to do the wrong thing. And that sort of deliberate misjudgment on the part of leadership, on the part of oligarchs, on the part of the political elite, I think will make it so the United States is judged poorly."
Professor Casagranda delivers a sweeping indictment of American foreign policy, cataloging overthrown democracies from Iran to Chile and wars from Vietnam to Iraq as deliberate wrong choices by elites. He argues the US squandered its post-Cold War opportunity for peace by ramping up defense spending under Clinton and Bush. The critique positions America's global role as fundamentally destructive rather than benevolent.

About this episode

Piers Morgan assembles leading historians including Lord Andrew Roberts, Douglas Brinkley, Roy Casagranda, and Barry Strauss to examine America at its 250th anniversary amid deepening cultural and political divisions. The discussion reveals fundamental disagreements about American identity, with Professor Casagranda arguing Trump's election represents a reactionary rejection of racial and gender equality progress, characterizing MAGA as an attempt to return to 19th century values. Presidential historian Douglas Brinkley dismisses Trump's historical significance despite his unprecedented celebrity reach, predicting his legacy will be reduced to commercial kitsch rather than ranking with Lincoln or FDR. The panel debates whether America has been a force for good globally, with Casagranda delivering a sweeping indictment of post-WWII foreign policy as deliberately destructive, citing overthrown democracies and unnecessary wars from Vietnam to Iraq. The Iran war emerges as a central case study of American military overreach, with historians suggesting Israel persuaded Trump into action based on faulty predictions about regime collapse and popular uprisings that never materialized. Barry Strauss predicts the US may soon end military aid to Israel, noting many Israelis want independence from American support. Lord Roberts argues FDR was America's greatest president for saving the world from Nazism, while noting Trump actually wields more executive power than King George III did. The conversation reveals how even American history itself has become contested territory in culture wars, with competing narratives about the nation's founding, its role in the world, and its future direction. Morgan notes Trump shared a post claiming he's the most powerful person ever to walk the planet, though historians remain skeptical of such grandiose claims despite acknowledging the American presidency's unprecedented global reach in the social media age.
