Historian David Nasaw tells the story of more than a million people stranded in defeated Nazi Germany after World War II. Some felt they couldn't return to their home countries under Soviet control. Others were Jewish survivors who had no homes to return to. Nasaw's book is 'The Last Million.'
Ali Soufan investigated terrorism cases and opposed the CIA's use of torture following the Sept. 11 terror attacks. After a legal battle, the redacted material in his 2011 memoir, Black Banners, has been restored.
