It seems that America and Britain and everybody else knew that the Japanese were up to something long before that infamous day in history. Could it have been prevented? Why didn't they listen? Who knows now? Much like the events of September 11, 2001, people in power appeared to have ignored or misplaced their suspicions about any such attack. Why don't people in power listen? Why didn't we? We will never know the truth. Maybe American politicians thought it wouldn't happen but I disagree. They rather it happened then not at all. It was the middle of the great depression and America wasn't involved in World War II. Had America got involved sooner? How many lives would have been saved? We will never know the truth. This BBC documentary offers the interviews and depicts the FDR administration as having some knowledge of a possible attack. Why am I not surprised at all? Maybe it's because the same thing happened on September 11, 2001. Of course thousands died needlessly and tragically. Many others suffered the loss of their relatives, friends, colleagues, and neighbors. Unless we learn from attacks on Pearl Harbor and September 11, 2001, we will never prevent another attack. It's sad and tragic. Maybe that's why this documentary shows another side beside the loss and that's that it could have prevented in the first place.
