Book excerpt: Almost one hundred years after World War I and the Russian Revolution, U.S. diplomat DeWitt Clinton Poole's (1885-1952) perspective on his experiences negotiating with Bolshevik authorities and monitoring anti-Bolshevik movements throughout the Soviet Union is now fully accessible. Through Poole's perspective, a key figure in U.S.-Soviet relations, this book sheds new light on the Russian Revolution and World War I.
