This week, Kelly is joined by historian and journalist Stephen Kinzer to discuss his book The True Flag: Theodore Roosevelt, Mark Twain, and the Birth of American Empire. They dig into the Spanish-American War, the fierce imperialist vs. anti-imperialist debate it sparked, and how those same arguments still echo through American foreign policy today.

What if the Civil War's most consequential diplomacy didn't happen in London or Washington — but in the back offices of Bahamian merchants, the shipyards of Liverpool, and the harbors of Nassau? In this episode, Kelly McFarland sits down with historian and Army veteran Beau Cleland to discuss his award-winning book "Between King Cotton and Queen Victoria: How Pirates, Smugglers, and Scoundrels Almost Saved the Confederacy" — winner of the 2026 Wiley Silver Prize for the best first book in the history of the Civil War.

Beau reveals how a decentralized network of blockade runners, private merchants, and colonial opportunists gave the Confederacy a fighting chance — and why their ultimate failure holds surprising lessons for gray zone conflict today.

From Iran's visa saga to sky-high ticket prices, heat waves in Kansas City, and FIFA's delicate dance with the White House, this tournament is anything but simple.

King Charles visited the White House — and it went exactly as planned. But did it actually matter?

In this episode of Diplomatic Immunity, we break down King Charles's state visit to the United States, what it reveals about how the British government has learned to work with Trump, and why the royal charm offensive doesn't necessarily translate into real policy wins for the UK.

We also cover:

• Trump's upcoming visit to China and what's at stake
• The latest from the US-Iran conflict
• The growing political crisis facing Keir Starmer back home

The special relationship is alive — but is it useful?

In this episode of Diplomatic Immunity, our host Kelly McFarland sits down with Dr. Amy Greenberg, professor at Penn State and author of A Wicked War: Polk, Clay, Lincoln, and the 1846 U.S. Invasion of Mexico, to explore one of the most consequential — and least remembered — wars in American history.

We trace the origins of the Mexican-American War from the Texas Revolution and the annexation debate, through James K. Polk's deliberate provocation of conflict, to the rogue diplomacy of Nicholas Trist, whose defiance of presidential orders ultimately shaped the modern American Southwest.

Topics covered:

• How US settlers in northern Mexico set the stage for Texas independence
• Why Texas remained unannexed for nearly a decade
• James K. Polk: the first "dark horse" president and the architect of Manifest Destiny
• The deliberate start of war — and Polk's lies to Congress
• Abraham Lincoln's spot resolutions and the rising anti-war movement
• The forgotten figure John Hardin and his connection to Lincoln's rise
• The US occupation of Mexico City and the "All of Mexico" movement
• Nicholas Trist's defiant negotiation of the Treaty of Guadalupe Hidalgo
• Why there is no monument in Washington, DC to this war — and why America forgot it

In this episode of Diplomatic Immunity, host Kelly McFarland sits down with presidential historian Lindsay Chervinsky, executive director of the George Washington Presidential Library at Mount Vernon, to explore one of the most consequential partnerships in American foreign policy history: James Monroe and his Secretary of State, John Quincy Adams. They dig into the origins of the Monroe Doctrine, why Adams famously turned down a British alliance offer, and what it actually meant to declare the Western Hemisphere off-limits to European imperial expansion in 1823. From the Adams-Onís Treaty to the Greek War of Independence, this conversation reveals just how much of early American foreign policy was shaped by Adams' extraordinary global experience — and why his vision remains remarkably relevant today. Topics covered:

• The Monroe-Adams partnership and the post-War of 1812 landscape
• The Adams-Onís Treaty and the acquisition of Florida
• The origins and three components of the Monroe Doctrine
• Why did Adams reject the British alliance offer Adams' famous July 4th address: "America does not go abroad in search of monsters to destroy"
• John Quincy Adams' presidency and his forward-thinking approach to Latin American alliances
• Why the Monroe Doctrine keeps coming back — and why context matters
