While the Empire of Japan was preparing for war with America in 1941, Emperor Hirohito often spoke of the awesome consequences of their decisions. (Keegan) The Emperor foresaw that Japan's actions would be a key determinant of the war's progress. Japan came to realize through careful analysis that war with America was inevitable if they wished to continue their conquest of East Asia. (Keegan) After this became obvious, the Japanese began planning the Attack on Pearl Harbor. By staging a surprise attack, Japan hoped to gain an upper hand and cripple America's ability to wage war. (Keegan) History tells us that the Japanese plan was unsuccessful; America was eventually able to regain its military capabilities and ultimately defeat Japan. But this does not mean that the Japanese decision was illogical. Our research question is whether or not the Japanese decision to attack America at Pearl Harbor was a good decision. This is an important topic because of the profound impact this decision has had on twentieth century history. It facilitated the American entry into the Second World War, thereby altering the course of the war in favor of the Allies. This was a major turning point in the war; without it, the Axis may very well have been victorious. Had the Japanese decided differently, we would be living in a completely different world. Our presentation will carefully analyze Japan's decision making process and evaluate thier ultimate conclusion to attack the United States. First, Alex will give a timeline of events. Next, James will do a geospatial analysis and link analysis. Finally, Taylor will perform evidence analysis using the PROACT method.
