No book is an island. Books are read and interpreted in the midst of other books, and their position in the stream of scholarship often determines what we say about them. In other words, history is written by winners.
Losers have a hard time getting their story told.
The Forgotten Holocaust tells the story of a nation which fought on the Allied side in World War II but emerged from the war a loser, even though the Allies won. In 1945, Poland was reoccupied by its sworn enemy, Soviet Russia. Authentic Polish voices were silenced, and Polish scholarship on World War II was virtually gagged. While the Jewish Holocaust lasted four years, terror in Poland lasted for fifty years, from 1939 to 1989. It is in this context that one should read Lukas' book.
