Since the events of September 11, 2001, Americans have done a great deal of soul-searching about what the future role the United States will play in international affairs. In many ways, any response to such an inquiry will contain many different layers and ideas. In April 2007, PBS began their investigations into this complex area by showing the first episode of "America at a Crossroads". Through eleven independently produced documentaries, the series hopes to explore topics such as the experience of American troops stationed abroad and global perspectives on America's role overseas. On the series' website, visitors can view clips from the various documentaries, take a look at some video diaries, and explore an interactive timeline that covers such topics as "The War in Iraq" and "Middle East Modern History". The site is rounded out by a discussion guide which serves as a jumping-off point for groups who which to discuss the issues raised by these programs.
