Is the Iran war about to end?

Donald Trump says the United States could be “out of Iran pretty quickly”, with the option of returning for “spot hits”, even as he escalates his criticism of Nato allies and questions America’s future in the alliance. His Secretary of State, Marco Rubio, is amplifying that message despite having backed legal safeguards preventing a US exit from Nato only two years earlier.

In this episode of TrumpWorld, Matt Frei and Anushka Asthana examine why this rupture feels different, how Trump’s frustration over the Iran war is driving the rhetoric, and what diplomats in London and Washington are saying privately about the strain. They also speak to lawyer and political scientist Anne-Marie Slaughter, CEO of New America and former State Department official under Hillary Clinton.
