Oil may dominate the headlines about the Middle East, but the real power often flows through water. Three narrow passages - the Suez Canal, the Strait of Hormuz, and Bab el-Mandeb – shape how the world moves. In times of crisis, they've become chokepoints, disrupting global trade, rattling markets, and shifting the balance of power way beyond the region. In this episode, three stories from these waterways… how they've helped define the modern Middle East and, as we've seen recently with Hormuz, the economic currents that affect us all.

Guests:

Alex Von Tunzelmann, author of Blood and Sand: Suez, Hungary, and Eisenhower's Campaign for Peace

Harold Lee Wise, author of Inside the Danger Zone: The U.S. Military in the Persian Gulf, 1987-1988

Farea Al-Muslimi, Yemen and Gulf researcher at Chatham House in London

Threats against public officials have become much, much more common. This includes everyone from the president of the United States to members of Congress, to state and local officials, and even civil servants like local librarians. Threats have always been a part of United States history, often manifesting in times of political turmoil or cultural tension. The internet age opened a new chapter in the U.S. making threats easier to make and harder to trace and prosecute. So what exactly is the standard for defining a criminal threat? How has it changed? And how do we balance safety and free speech in a world where the two seem increasingly at odds? On this episode of Throughline, the shifting line between protected speech and true threats.

Guests:

David L. Hudson, Jr., associate professor of Law at Belmont University Law School and First Amendment fellow for the Freedom Forum

Mary Anne Franks, professor at The George Washington Law School, and author of Fearless Speech and The Cult of the Constitution
