Listen in to a debate on the Chinese-Soviet alliance during the Korean War, as featured on the weekly CNN program "Postscript" -- which accompanies the COLD WAR series.

CNN World Affairs Correspondent Ralph Begleiter, joined by Russian historian Vladislav Zubok and American scholars Kathryn Weathersby and Thomas Blanton, consider if the United States misread the ties between Moscow and Beijing at the time of the Korean War.

Dr. Vladislav Zubok is one of the leading historians of the Soviet side of the Cold War and the author of "Inside the Kremlin's Cold War." He has studied extensively in Soviet and American archives and has taught classes on the Cold War at Amherst College, Ohio University in Athens and Stamford University. In 1993, Zubok was employed by the Kennan Institute for Advanced Russian Studies in Washington, D.C., and since then has worked at the Norwegian Nobel Institute in Oslo and is now a fellow at the National Security Archive in Washington.

Kathryn Weathersby is a specialist in modern Russian and East Asian history. She became one of the first scholars to obtain access to Soviet archival documents on Moscow's role in the Korean War and Soviet involvement in Korea prior to the war.

Thomas Blanton is executive director for the National Security Archive in Washington, D.C. The NSA is a non-governmental research institute providing information from U.S. government and official archives for scholars, journalists, members of Congress, lobbyists and others. Their research teases out documents still classified to give a complete picture of what really happened.
