Which would likely be the least biased account of the December 7, 1941, attack on Pearl Harbor?

A 2014 world history textbook would likely be the least biased because it was written long after the attack, allowing historians to review evidence and multiple perspectives. The Japanese article, Roosevelt’s speech, and the announcer’s report were produced close to the event and could reflect national interests, political goals, or the confusion of the moment. The textbook’s account is therefore most likely to offer a measured historical perspective.
