1. All of the following are examples of aggressive actions taken by Japan before World War II EXCEPT:
The Pearl Harbor attack occurred in 1941, during the course of World War II. The other events were precursors of what became World War II.
2. Until the attack at Pearl Harbor, most Americans felt that the United States should not get involved in World War II.
Of course, that feeling changed immediately after the attack on Pearl Harbor.
3. World War II was considered a war of attrition due to the emphasis on defense.
World War I had been like that, a war of attrition, dug in on the lines of the front. But World War II saw the German blitzkrieg of offensive attacks, as well as much aggressive expansion by Japan. The Allies responded with aggression military offensives of their own.
