This episode turns to one of history's darkest chapters—and to America's complex, often painful role in confronting it. We trace the unfolding of the Holocaust alongside the question that haunted the United States: What did Americans know, and when? From immigration barriers to hesitant policymakers, from scattered warnings to the liberation of camps, this story reveals a nation wrestling with moral responsibility at a moment when the stakes could not have been higher. It's a sobering but essential journey into the limits of awareness, the consequences of inaction, and the urgent reminders the past still offers today.
