As the United States reshaped Manifest Destiny for use in the 20th century, the concept came to be equated not with conquest and expansion, but with the spread of American values and institutions. Focusing on World War I and the Russian Revolution, the section "A New World Order" traces the deflected trajectory of President Wilson's idealistic plan to export democracy - a plan that ended in compromises and broken dreams. "Containment," which begins with World War II, examines the spread of communism in Asia and U.S. opposition to it via the Kennan policy of containment and the Truman Doctrine. And "Quagmire" discusses how the Kennedy and Johnson administrations felt duty-bound to escalate American political and military involvement in Vietnam as a part of an ideological proxy war between East and West. Historians Jeremi Suri, Erez Manela, H. W. Brands, George C. Herring, Jessica Elkind, Walter LaFeber, John Milton Cooper, and Mark Philip Bradley are featured. Produced by Lucasfilm Ltd. A part of the series Manifest Destiny.
