Problem
One day you are walking down the street when a TIME TRAVELER appears in front of you! Amazing! The time traveler is very interested in the Pacific War. But, he is confused by one thing: why did the Japanese attack Pearl Harbor in 1941?! The time traveler offers to take you back in time to visit two important events that contributed to eventual attack on Pearl Harbor. He tells you that you can choose any two events that took place between the years 1910 and 1941 and they should be the events that you think were most important in leading to the attack. So, which would you choose?
