As Japan approached a military conflict with the West during the late twenties’ and thirties’, Yamamoto also gained a reputation for being overtly opposed to it. It is difficult to comprehensively address why Japan favored war with the U.S. and Britain, and it is equally difficult to track all the political entities of her leadership that lead her to this decision. However, Japan’s friendly relations with the U.S. at the turn of the century had by this time eroded. Japan generally believed she was not shown the respect due her as an "equal by the Western World." Her religious beliefs and extensive military history of sweeping victories provided her with an unshakable self-assurance. Additionally, the army and navy were not entirely under the control of the civilian parliament. Though much of the senior leadership of the navy was opposed to war, many junior officers, who had an appetite for the glory of conquest, had more influence collectively on the decisions to be made. Should the Admirals or Generals dissent, as did Yamamoto, they risked assassination (Dull 5). "It was the combination of the Japanese way of thinking, Japan’s past history, her pride, and the peculiar nature of her political process, which produced the decision for war-the decision was not made by any one man, or caused by any one event. It was left up to the armed forces to continue to make plans which would increase the chances for victory" (Dull 6). Having spent extensive time in the U.S., Yamamoto knew that during a lengthy campaign American industrial capacity would easily overwhelm that of Japan’s and he earnestly resisted such a conflict. As the Navy’s Vice Minister, he was continually under the threat of assassination as this position enabled him to oppose the efforts of the army to lead the nation in to war. Yamamoto was very vocal about remaining outside the Tripartite Pact with Germany and Italy, as this would provoke the U.S. (Ito 16). In an effort to keep Yamamoto from being killed Admiral Yonai had him promoted to Commander in Chief of the Combined Fleet. In doing so he had removed Yamamoto from the political arena were he was at risk, but he also removed wise and stalwart leadership were it was needed most (Potter 36). "Had Yamamoto remained in Tokyo he would have gladly risked his life in opposing the German alliance and war against Great Britain and the United States. It was unfortunate for Japan and the world that he was on board his flagship. Without the Navy the Army could not have started a war no matter how loudly the sabers rattled" (Ito 18).
