Why It Matters

The piece highlights a core democratic and strategic problem: absent congressional authorization, military actions risk lacking public legitimacy, long-term political support and legal accountability, increasing the chance of unstable or unlawful conflicts. Restoring constitutional processes matters for both U.S. credibility and the humane conduct of war.

Summary

David French, drawing on his JAG and constitutional experience, argued that the law of armed conflict is real, enforceable and rooted in centuries of practice designed to limit violence and prevent unnecessary wars. He said U.S. constitutional rules reserve the power to declare war to Congress, and bypassing that process—citing recent tensions with Iran—undermines both democratic accountability and the effectiveness of military campaigns. French warned that unilateral executive military action cuts the public out of the debate, weakens sustained national support, and risks eroding norms that make war more humane. He acknowledged historical complexities, but framed the congressional role as essential to legitimate and durable use of force.

Content warning: This conversation includes some graphic descriptions of violence and sexual violence.
David French, New York Times columnist, Iraq War veteran, and constitutional lawyer, joins Scott to explain why he believes the Iran strikes violated the Constitution — and why that's not a technicality.
They discuss what just war doctrine actually requires, why democracies that skip the constitutional process lose wars, and why the Pope's standoff with Trump is more consequential than it sounds.
