In a prime time address on Wednesday, President Trump proclaimed that America was “on the cusp of ending Iran’s sinister threat.” But he also kept open the option of boots on the ground. The effective closure of the Strait of Hormuz is also about to start really biting – as countries get hit with shortages, which would spike prices across the globe.

So what are Trump’s options? What would happen if he just declared victory and walked away from the fight? What kinds of military operations are on the table? If Trump ended the war without achieving his strategic goals, what would that mean for the United States, for Iran and for the world?

“I don’t see a victory in real terms at the end of this crisis…,” Suzanne Maloney told me. “And that is a very dangerous outcome for the long term.”

Maloney is one of Washington’s leading Iran experts. She has advised several presidential administrations and has written or edited a number of books on Iran. She is the vice president and director of the Brookings Institution’s foreign policy program.

Note: This conversation was recorded on Wednesday morning, before Trump’s speech on the war. But the speech reflected Maloney’s analysis almost perfectly.

Consciousness is this amazing, mind-bending riddle. It’s the only thing any of us truly knows. We experience everything else in life through it. And yet we barely understand it. We don’t know what it’s made of or how it works or why it exists.

But scientists and theorists have been trying to answer those questions, and have made some startling discoveries. The science writer Michael Pollan, known for books like “The Omnivore’s Dilemma” and “How to Change Your Mind,” spent five years on the vanguard of this research. And his new book, “A World Appears: A Journey Into Consciousness,” shows that the closer you look at consciousness, the weirder it gets.

I asked Pollan to walk through some of the places his mind wandered on this journey — including the role of the body and feelings in consciousness, fascinating studies that provide evidence for plant sentience, the researchers who have abandoned their old theories after trying psychedelic drugs, and the possibility that consciousness may not emerge from inside us at all. “I’ve entered this ‘never say never’ realm with this research,” Pollan told me.

Is Trumpism crashing on the shoals of the Iran war?

That is what Christopher Caldwell thinks. Caldwell is a prominent thinker on the right. He’s a contributing editor at the conservative publication the Claremont Review of Books,and he’s one of the people who’ve been trying to define, and even craft, a coherent Trumpism. So his recent article in The Spectator, “The End of Trumpism,” sparked a lot of debate on the right.

At the core of this debate are some fundamental questions that I think remain unresolved, despite Trump’s decade-long dominance of the Republican Party: What is Trumpism? Is there Trumpism, or is there just Donald Trump?

Caldwell is a contributing writer for Times Opinion and the author of “The Age of Entitlement: America Since the Sixties.” In this conversation, he explains how he understood Trumpism as a movement of “democratic restoration” — and why he believes the Iran war betrays that. And I ask him why he sees the seams of Trump’s base fraying, despite polling that suggests otherwise.

Every Tuesday and Friday, Ezra Klein invites you into a conversation about something that matters. How do we address climate change if the political system fails to act? Has the logic of markets infiltrated too many aspects of our lives? What is the future of the Republican Party? What do psychedelics teach us about consciousness? What does sci-fi understand about our present that we miss? Can our food system be just to humans and animals alike?
