Jay Winik, historian and New York Times bestselling author, spoke with Brian Kilmeade to discuss the risks involved in the proposed summit between President Trump and North Korean leader Kim Jong-Un. Winik points to three landmark summits in American history that President Trump can learn from: The Yalta Conference where President Franklin D. Roosevelt, British Prime Minister Winston Churchill and Soviet Union Premier Joseph Stalin met near the end of World War II, the two-day summit in 1961 when President John F. Kennedy traveled to Vienna to meet with Nikita Khrushchev and the 1986 summit between President Ronald Reagan and General Secretary of the Communist Party of the Soviet Union Mikhail Gorbachev in Reykjavik, Iceland.

Plus, Jay Winik on the lasting impact of Reconstruction after the end of the Civil War.
