Still, another point to consider is that the English, French, Dutch, Portuguese had Asian/Pacific colonies. The Japanese desired the same for its country as part of its increasing nationalism. One reason they regarded America negatively was because of its crippling embargo. Having fuel and raw materials was paramount for its quest for Pacific expansion and necessary for day to day living.
A declassified confidential 26 page memo is housed in the Franklin Delano Roosevelt Library that details an imminent attack in the Pacific. The memo was dated December 4, 1941. An abundance of theories exist on how much and what exactly did the US know before the attack. One thing is certain: The focus on code breakers after Pearl Harbor was to decipher military code as opposed to diplomatic code.
Pearl Harbor was a major turning point in American history. The Seven Major Events Prior to Pearl Harbor were pivotal factors that led to the America's entry into World War II. On December 7, 1941, 2400 people died. 1178 were injured. Hundreds of planes were destroyed and eight battleships were demolished. Without hesitation, the US declared war on Japan. Japan, Italy and Germany in turn declared war on the United States. The stage was now set.
