One of the earliest U.S. counterinsurgency campaigns outside the Western Hemisphere, the Siberian intervention was a harbinger of policies to come. At the height of World War I, President Woodrow Wilson dispatched thousands of American soldiers to Siberia, and continued the intervention for a year and a half after the armistice in order to overthrow the Bolsheviks and to prevent the Japanese from absorbing eastern Siberia. Its tragic legacy can be found in the seeds of World War II, and in the Cold War.
