Spy Wars

Former CIA agent and intelligence expert John Sipher talks with Sasha Rionda about the intriguing espionage program, “Spy Wars with Damian Lewis.”

The new docu series–which mixes re-enactments with actual KGB, CIA, FBI and MI6 interviews–explores thrilling stories from the Cold War and the Iran Hostage Crisis to the discovery of sleeper agents in the U.S.–which inspired the plot for “The Americans.”

“Spy Wars” airs Sunday nights at 8pm ET/PT on the Smithsonian Channel.
