In the mid-1930s, just as the United States was embarking on a policy of neutrality, Nazi Germany embarked on a program of espionage against the unwary nation. Hitler’s attempts to interfere in American affairs by spreading anti-Semitic propaganda, stealing military technology, and mapping US defenses. Today’s guest is Rhodri Jeffreys-Jones, author of the book “The Nazi Spy Ring in America.” Using recently declassified material, he shows how Germany’s foreign intelligence service, the Abwehr, was able to steal top secret US technology such as a prototype codebreaking machine and data about the latest fighter planes. Enlisting the services of German-American fascists and anti-Semites, they resorted to ruthless methods to achieve their goals, including murdering the wife and daughter of an American industrialist. When the spy ring was busted in 1938 by FBI agent Leon Turrou, the ensuing trial caused a national sensation and played a significant role in shifting public opinion against Germany, awakening many Americans to the looming Nazi threat. This story provides essential insight into the role of espionage in shaping American perceptions of Germany in the years leading up to US entry into World War II and sheds light on a now-forgotten but significant episode in the history of international relations.See omnystudio.com/listener for privacy information.

Many great Mesoamerican civilizations existed before and long after the arrival of Christopher Columbus: The Incans, Mayas, and Aztecs. But there was one civilization in North America you likely never have heard of that could have been more advanced as any of them, a reached a level of China or Mesopotamian civilization.The Mississippian Culture of North America built a number of settlements in the centuries before Columbus arrived in the new world. The largest settlement, Cahokia, may have had up to 50,000 residents in 1200 A.D. This made it larger than contemporary London and Paris. The entire city was planned and built on a grid that matched with celestial events. In the center of the city was a mound made up of 22 million cubic feet of earth, making it nearly as impressive as the Great Pyramid of Giza. Native cultures north of Mesoamerica (in the modern-day US) on the cusp of becoming an advanced civilization? Many of the ingredients were there, and perhaps a little more mixing would have done it.See omnystudio.com/listener for privacy information.

When Kristin L. Hoganson arrived in Champaign, Illinois, after teaching at Harvard, studying at Yale, and living in the D.C. metro area with various stints overseas, she expected to find her new home, well, isolated. Even provincial. After all, she had landed in the American heartland, a place where the nation's identity exists in its pristine form. Or so we have been taught to believe. Struck by the gap between reputation and reality, she determined to get to the bottom of history and myth. The deeper she dug into the making of the modern heartland, the wider her story became as she realized that she'd uncovered an unheralded crossroads of people, commerce, and ideas. But the really interesting thing, Hoganson found, was that over the course of American history, even as the region's connections with the rest of the planet became increasingly dense and intricate, the idea of the rural Midwest as a steadfast heartland became a stronger and more stubbornly immovable myth. I’m speaking to Hoganson today, who is author of the book The Heartland: An American History. She tracks both the backstory of this region and the evolution of the idea of an unalloyed heart at the center of the land.See omnystudio.com/listener for privacy information.

Soon after atomic bombs exploded over Hiroshima and Nagasaki in 1945, MGM set out to make a movie studio chief Louis B. Mayer called “the most important story” he would ever film: a big budget dramatization of the Manhattan Project and the invention and use of the revolutionary new weapon.Over at Paramount, Hal B. Wallis was ramping up his own film version. His screenwriter: the novelist Ayn Rand, who saw in physicist J. Robert Oppenheimer the model for a character she was sketching for Atlas Shrugged.Today’s guest is Greg Mitchell’s, author of “The Beginning or the End,” and we discuss the first efforts of American media and culture to process the Atomic Age. A movie that began as a cautionary tale inspired by atomic scientists aiming to warn the world against a nuclear arms race would be drained of all impact due to revisions and retakes ordered by President Truman and the military—for reasons of propaganda, politics, and petty human vanity (this was Hollywood, after all).See omnystudio.com/listener for privacy information.

The cherished idea of United States as a unified country has been long believed. But today’s guest Colin Woodard argues that this is an invented tradition. He has argued for the existence of 11 separate stateless nations within the United States, where rival cultures explain the history, identity, and voting behaviors of the United States. At least 5 explanations for American ideology have existed, from Manifest Destiny to Frederick Douglas's civic nationalism. However, there is a vision of American that can bring us all together. In his new book “Union: The Struggle to Forge the Story of United States Nationhood,” he examines how the myth of our national unity was created and fought over by five men—George Bancroft, William Gilmore Simms, Frederick Douglass, Woodrow Wilson, and Frederick Jackson Turner—and how it continues to affect us today.If we’ve never been one America, but several, then where did the narrative of United States nationhood come from? Who came up with it, when, and why? How did it come to be accepted and at what point did it succeed in concealing the fragmented reality? In the 19th and early 20th century, a small group of individuals—historians, political leaders, and novelists—fashioned a history that attempted to erase the fundamental differences and profound tensions between the nation’s regional cultures. These men were creating the idea of an American nation instead of a union of disparate states—but their rosy vision was immediately contested by another set of intellectuals who claimed that if we are a nation at all, it is an ethno-state belonging to the allegedly superior Anglo-Saxon race. This concept eventually morphed into white supremacy and ethno-nationalism in people like Woodrow Wilson.The fight continues today but there are narratives that could unite all of us and that's what we'll discuss today.See omnystudio.com/listener for privacy information.

Before there were Navy SEALs, before there were Green Berets, there were the 40 Thieves: the elite Scout Sniper Platoon of the Sixth Marine Regiment during World War II. Behind enemy lines on the island of Saipan—where firing a gun could mean instant discovery and death—the 40 Thieves killed in silence during the grueling battle for Saipan, the "D-Day" of the Pacific. Now Joseph Tachovsky—today's guest and whose father Frank was the commanding officer of the 40 Thieves, also called "Tachovsky's Terrors"—joins with award-winning author Cynthia Kraack to transport readers back to the brutal Battle of Saipan. World War 2 Marines were the poorest equipped branch of the services at that time, and they were notorious thieves. To improve their odds for victory against the Japanese, they found it necessary to improve their supply chains through “Marine Methods,” stealing. Being the elite of the Sixth Regiment, the Scout-Sniper Platoon excelled at the craft—earning them the nickname of the “40 Thieves” from their envious peers. Upon returning from a 1943 trip to the Pacific theater, Eleanor Roosevelt observed, “The Marines I have met around the world have the cleanest bodies, the filthiest minds, the highest morale and the lowest morals of any group of animals I have ever seen. Thank God for the United States Marines.”See omnystudio.com/listener for privacy information.

The U.S. Constitution never established a presidential cabinet—the delegates to the Constitutional Convention explicitly rejected the idea. So how did George Washington create one of the most powerful bodies in the federal government?On November 26, 1791, George Washington convened his department secretaries—Alexander Hamilton, Thomas Jefferson, Henry Knox, and Edmund Randolph—for the first cabinet meeting. Why did he wait two and a half years into his presidency to call his cabinet? Because the U.S. Constitution did not create or provide for such a body. Washington was on his own.Faced with diplomatic crises, domestic insurrections, and constitutional challenges—and finding congressional help lacking—Washington decided he needed a group of advisors he could turn to. He modeled his new cabinet on the councils of war he had led as commander of the Continental Army. In the early days, the cabinet served at the president’s pleasure. Washington tinkered with its structure throughout his administration, at times calling regular meetings, at other times preferring written advice and individual discussions.Todays guest, Lindsay M. Chervinsky, author of the book The Cabinet: George Washington and the Creation of an American Institution, reveals the far-reaching consequences of Washington’s choice. The tensions in the cabinet between Hamilton and Jefferson heightened partisanship and contributed to the development of the first party system. And as Washington faced an increasingly recalcitrant Congress, he came to treat the cabinet as a private advisory body to summon as needed, greatly expanding the role of the president and the executive branch.See omnystudio.com/listener for privacy information.

James Monroe, America’s fifth president and the last chief executive of the Founding Father generation, lived a life defined by revolutions. From the battlefields of the War for Independence, to his ambassadorship in Paris in the days of the guillotine, to his own role in the creation of Congress's partisan divide, he was a man who embodied the restless spirit of the age. He was never one to back down from a fight, whether it be with Alexander Hamilton, with whom he nearly engaged in a duel (prevented, ironically, by Aaron Burr), or George Washington, his hero turned political opponent. Today’s guest, Tim McGrath, author of James Monroe: A life, discusses the epic sweep of Monroe’s life: his near-death wounding at Trenton and a brutal winter at Valley Forge; his pivotal negotiations with France over the Louisiana Purchase; his deep, complex friendships with Thomas Jefferson and James Madison; his valiant leadership when the British ransacked the nation’s capital and burned down the Executive Mansion; and Monroe’s lifelong struggle to reckon with his own complicity in slavery. Elected the fifth president of the United States in 1816, this fiercest of partisans sought to bridge divisions and sow unity, calming turbulent political seas and inheriting Washington's mantle of placing country above party. Over his two terms, Monroe transformed the nation, strengthening American power both at home and abroad.See omnystudio.com/listener for privacy information.

At the dawn of the twentieth century, when human flight was still considered an impossibility, Germany's Count von Zeppelin vied with the Wright Brothers to build the world's first successful flying machine. As the Wrights labored to invent the airplane, Zeppelin fathered the wondrous airship, sparking a bitter rivalry between the two types of aircraft and their innovators that would last for decades in the quest to control one of humanity's most inspiring achievements. And it was the airship--not the airplane--that would lead the way. In the glittery 1920s, the count's brilliant protégé, Hugo Eckener, achieved undreamt-of feats of daring and skill, including the extraordinary round-the-world voyage of the Graf Zeppelin. What Charles Lindbergh almost died doing--crossing the Atlantic in 1927--Eckener effortlessly accomplished three years before the Spirit of St. Louis even took off.I'm talking to Alexander Rose, author of the new book “Empires of the Sky,” which gets into this story. Even as the Nazis sought to exploit Zeppelins for their own nefarious purposes, Eckener built his masterwork, the behemoth Hindenburg--a marvel of design and engineering. Eckener met his match in Juan Trippe, the ruthlessly ambitious king of Pan American Airways, who believed his fleet of next-generation planes would vanquish Eckener's coming airship armada. It was a fight only one man--and one technology--could win. Countering each other's moves on the global chessboard, each seeking to wrest the advantage from his rival, the two men's struggle for mastery of the air was not only the clash of technologies, but of business, diplomacy, politics, personalities, and their vastly different dreams of the future.See omnystudio.com/listener for privacy information.

In the middle of World War II, Nazi military intelligence discovered a seemingly easy way to win the war for Adolf Hitler. The three heads of the Allied forces—Franklin Roosevelt, Winston Churchill, and Josef Stalin—were planning to meet in Iran in October 1943. Under Hitler's personal direction, the Nazis launched “Operation Long Jump,” an intricate plan to track the Allied leaders in Tehran and assassinate all three men at the same time. “I suppose it would make a pretty good haul if they could get all three of us,” Roosevelt later said. The plan failed, but what if it had succeeded?Perhaps some good could have come out of it, namely a less brutal Soviet premier who killed millions. But many frightening scenarios also emerge, such as an American-Soviet pact against Europe, or a Cold War that goes hot in the 1950s. In the infinite alternate timelines that include a successful assassination of theBig Three, most of them are bad.See omnystudio.com/listener for privacy information.
