“We’ll either save, or doom, the planet, during the Trump administration.” That’s what Bill McKibben says—he’s an organizer of the Climate March in Washington on Saturday, April 29.

Also: 81 percent of white evangelicals voted for Trump, despite his obvious failings as a Christian. Frances Fitzgerald examines evangelicals’ earlier history in politics, including their support for a Democrat—the “born-again” Jimmy Carter. Her new book is The Evangelicals: The Struggle to Shape America.

Plus: Andrew Bacevich looks at America’s longest war. Our fight in Afghanistan, which began 15 years ago, shows no sign of ending, despite the recent dropping of “the mother of all bombs.”
