The document discusses the 1941 Japanese attack on Pearl Harbor and the subsequent American entry into World War 2. It analyzes the 1942 film "Tora! Tora! Tora!" about the Pearl Harbor attack, noting several historical inaccuracies presented in the film that seem intended to glorify American forces and downplay Japanese resistance. The document questions whether historical truth can be obtained from films, as the perspectives are often limited and biased depending on who produces the film.
