  • Fault Lines Episode 547: Tilting at Windmills in Greenland?
    Jan 21 2026

    Today, Les, Jamil, Morgan, and Jess discuss Greenland as President Trump arrives at the World Economic Forum in Davos and once again places the Arctic island at the center of global attention. While Trump’s rhetoric has sparked backlash across Europe, the debate raises serious strategic questions: Greenland’s growing importance to U.S. national security, its role in Arctic defense, and why Washington has sought greater influence over the territory for more than a century.


    Should we be wringing our hands or rending our garments over the Kerfuffle with Europe? Does the United States have a legitimate national security interest in Greenland, and if so, what’s the right way to pursue it without fracturing NATO unity? How should Washington balance pressure with reassurance to allies already rattled by the war in Ukraine? And as Trump enters his second year in office, what does the Greenland debate tell us about how this administration plans to wield power going forward?

  • Episode 546: Fun Friday: America’s Best (and Worst) Foreign Policy Calls
    Jan 16 2026

    Today, Jess, Les, Andrew, and Joshua take a step back from the headlines for a Fun Friday roundtable on the best and worst American foreign policy decisions, inspired by a recent Council on Foreign Relations article drawing on conversations with the Society for Historians of American Foreign Relations. From the Marshall Plan and Bretton Woods to PEPFAR and the peaceful end of the Cold War in Europe, the team reflects on moments when U.S. leadership, economic power, and long-term thinking paid real dividends.


    What separates foreign policy successes from failures? Why do some hard-power decisions look effective at first but unravel over time? And as the U.S. looks ahead, what should decision-makers keep firmly in mind before reaching for any one instrument of power?


    Check out the article that helped shape our Fellows’ discussion:

  • Episode 545: The U.S. Weighs It’s Iran Options
    Jan 14 2026

    Today, Les, Jamil, Morgan, and Andy revisit Iran as protests continue to escalate and the reported death toll climbs into the thousands. President Trump was briefed this week on response options and has publicly signaled support for demonstrators, saying that “help is on the way.”


    What does meaningful support for Iranian protesters actually look like? Should the United States openly back regime change—and if so, how, given limited military presence and a fractured opposition? Are covert action, cyber operations, and coordination with regional partners more realistic tools than overt force? And as Trump isolates Iran economically and diplomatically, is this the beginning of a pressure campaign that could genuinely tip the balance, or another moment of outrage without follow-through?
