Post One: True stories from Marine Embassy Guards

This conversation dives into the complex story of Clayton Lonetree, a Marine Security Guard whose romance with a KGB asset spiraled into one of the Cold War’s most debated espionage cases. Author Rodney Barker—whose book Dancing with the Devil: Sex, Espionage and the U.S. Marines: The Clayton Lonetree Story remains the definitive account—unpacks the human side of the scandal: loneliness, identity, and the seduction of feeling like “the exception.” We trace the relationship with Violetta and “Uncle Sasha,” the slow-burn tradecraft, Lonetree’s Vienna confession, and the bruising interagency investigation that followed. Along the way, Barker separates myth from fact (including the detachment-wide rumors) and situates the case alongside bigger intelligence failures of the era—offering practical lessons for today’s Marines about recruitment, social engineering, and safeguarding embassies without paranoia.

In this episode, Former State Department Counterintelligence expert and RSO Robert Booth draws on decades of experience in diplomatic security to reveal the hidden world inside U.S. embassies. He explains how Marine Security Guards serve as the frontline eyes and ears for counterintelligence, why foreign spy services actively target them, and what makes them both an asset and a vulnerability. Booth walks through real-world cases — including the Clayton Lonetree espionage scandal and the Aldrich Ames betrayal — and breaks down how social media and platforms like LinkedIn have reshaped the modern espionage landscape.Leaks Spies and LiesState Department Counterintelligence: Leaks, Spies, and Lies

In April 1975, as South Vietnam collapsed, the Marines at the U.S. Consulate in Can Tho faced a mission no one had trained for: evacuating by boat.
