Tom Crouch at "A More Perfect Union" Exhibit, by Strauss, Richard, 1989, Smithsonian Archives - History Div, Curator Tom Crouch stands in front of part of the "A More Perfect Union: Japanese Americans and the United States Constitution" exhibit at the National Museum of American History. The exhibition, which opened on October 1, 1987, was designed to focus attention on the Bicentennial of the Constitution and explore a period when racial prejudice and fear upset the balance between the rights of citizens and the power of the state and led to the internment of some 120,000 Japanese Americans for much of World War II. The exhibition also includes a section on the men in the 100th Battalion/442nd Regimental Combat Team, an all-Japanese American unit of the U.S. Army..
