Which would likely be the least biased account of the december 7, 1941, attack on pearl harbor?

president franklin d. roosevelt’s speech following the attack
a japanese news article published on december 8, 1941
a world history textbook’s account published in 2014
a radio announcer’s account from pearl harbor at the time of the attack

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
