American Views the Holocaust, 1933-1945, A Brief Documentary History, by Robert H. Abzug (TPB, 1999, $2)
"Careful research has opened painful questions of national conscience and reputation and has led to a profound rethinking of the past. Historians have long since disproved the heroic view of the Allies as simply innocent liberators. Clearly, the Allies had fairly complete knowledge of the Nazi genocide as it happened, and only a few scholars have argued that the Allies could not have done more to save at least some Jews before the end of the war."
Still another view we weren't told about in school. Read this book and see what you think. See it in the WWII section, avail. 12/7. (Beware: VERY small print!)
