Episode 440: U-Turns and Uncertainty – The Trump Administration’s Iran Dilemma

Today, Martha, Les, Andy, and Jess unpack the Trump administration’s latest mixed signals on Iran. After U.S. Special Envoy Steve Witkoff publicly suggested the U.S. might accept uranium enrichment at levels allowed under the JCPOA, the statement was quickly walked back—raising major questions about whether the administration has a coherent strategy for talks with Tehran.


What is the Trump administration’s actual position on Iran’s nuclear program? Is Witkoff—despite his lack of diplomatic experience—shaping U.S. foreign policy by default? Can the U.S. pursue negotiations without clear parameters, or should it return to a maximum pressure campaign?


Check out the answers to these questions and more in this episode of Fault Lines.

Episode 439: Burn It Down—Marocco’s Exit and the Future of U.S. Foreign Aid

Today, Les, Martha, and Jess unpack the surprise departure of Pete Marocco, Director of the Office of Foreign Assistance, the architect behind the Trump administration’s dismantling of U.S. foreign assistance. In less than three months, USAID has been effectively gutted, with over 6,000 programs under review and thousands of jobs in the U.S. and abroad at risk. Marocco’s approach—mirroring Elon Musk’s soon-ending stint at DOGE—has thrown American aid policy into turmoil just as China deepens its influence in key developing regions and Congress begins to push back on the administration’s agenda.


Was Marocco’s removal part of a broader shift—or just the end of a mission to dismantle American aid? Who’s actually calling the shots now, and could this signal a shift to a more measured approach to foreign assistance? And as U.S. credibility erodes abroad, will rivals like China turn this moment of disarray into a permanent strategic advantage?

European security U.S. troop withdrawal Russia China defense investments Ukraine conflict transatlantic relationship

Today, Jess, Morgan, Amy, and Algene dive into the shifting dynamics of European security as the Trump administration reportedly considers withdrawing up to 10,000 U.S. troops from the continent, while the head of U.S. European Command and several members of Congress urge against a drawdown. At the same time, European allies are boosting their defense investments, Ukraine is accusing China of direct involvement in the conflict, and the broader transatlantic relationship faces a potential realignment.


What would a U.S. troop withdrawal signal to Russia and China? Is Europe prepared to fill the gap if the U.S. steps back? Could a force reduction undermine ceasefire efforts in Ukraine—or is this an opportunity for Europe to redefine its role in regional security?

Cobalt Conflict Congo U.S. Strategy minerals-for-security deal Rwandan-backed rebel groups natural resources regional tensions Trump administration Africa strategy

Today, Martha, Les, Bishop, and Amy discuss the Democratic Republic of the Congo’s plea for a minerals-for-security deal with the United States, as the country faces mounting violence and instability. With $24 trillion worth of natural resources—including critical cobalt reserves—on the line, Rwandan-backed rebel groups have seized key mining hubs in eastern Congo, killing thousands, displacing millions, and igniting regional tensions.


What’s in it for Washington, and can the Trump administration craft a consistent, credible Africa strategy? As Rwanda and Uganda continue to exploit the chaos and U.S. tariffs hamper global engagement, will this become another case where talk outpaces action? And with American companies reluctant to invest in conflict zones, is the DRC poised to become another lost front in the race for critical minerals?

tariffs global fallout President Trump America First alliances national security global supply chain China Japan South Korea Israel

Today, Les, Martha, and Jess unpack the growing global fallout from President Trump’s expanding tariff agenda. With a minimum 10% tariff imposed on all imports – and significantly higher rates hitting key partners like Vietnam and the European Union – the administration’s “America First” approach is straining alliances and undercutting strategic objectives.


Will Congress push back before economic strain turns into political blowback? Can national security priorities withstand the ripple effects of a disrupted global supply chain? And as China retaliates and allies like Japan, South Korea, and Israel respond, is Trump’s trade strategy isolating America at a time when unity is essential?
