Japanese expansion The lack of civilian control of the military and, indeed, the government began to tell in the early 1 9 30s. The alleged murder of a Japanese officer in the Chinese city of Mukden and the staged explosion on a nearby Japanese- owned rail line gave the Japanese military a pretext to occupy Manchuria. The reality is that far from an act of Chinese aggression, It was the act of a rogue Japanese military unit. Nevertheless Tokyo supported the expansion and by 1 9 32 had set up a protectorate called Manchukuo under the puppet Chinese emperor Pu Yi. The Chinese government complained bitterly to the League of Nations. While there seemed a political will on the part of the smaller members of the League to act, they had little means to do so. The US urged the League to enforce the Kellogg-Briand Pact to which both China and Japan had been signatories. Unwilling to commit any troops to Manchuria, the League sent the Lytton Commission to investigate and compile a report. The report placed blame on both the Chinese and the Japanese. It also found, however, the resulting territory of Manchukuo to be illegitimate and in violation of the Nine Power Treaty. As a result of the report the Japanese withdrew from the League. The League had clearly failed its first major test. Collective security had failed to prevent a state from using force to expand at the expense of a weaker neighbour. Economic sanctions were unpalatable to the powers given the fragile state of the global economy. Garnering support for a military adventure to defend a remote part of China only 12 years after the last war and given the economic state of the powers was likewise an impossibility. Understanding the essential weakness of the League, the Japanese government went further, issuing the Amau D octrine declaring China to be within the Japanese sphere of influence and calling on all other countries to remove themselves from all Chinese economic and political affairs. This was a clear rej ection of both the "Open Door" policy and the US Stimson Doctrine of 1 9 32, which stated that the US would not recognize any treaty that infringed on US commercial rights in the region. The Japanese invasion of Manchuria and the West's inability to stop it was illustrative and set the stage for international relations for the rest of the 1 9 30s. Agreements and treaties were only useful insofar as countries were willing to back them up with force. In the difficult economic times of the 1 9 3 0s, states would choose to protect trade at the expense of national self-determination. It was a lesson learned by the future Axis Powers, but not the future Allied Powers. It also illuminated the degree to which US and Japanese policy in the region was contradictory. Should each of these countries continue along its foreign policy path, it was hard to see how they would not come into some sort of conflict. Sino-Japanese Wa r and US rea ction In February of 1 9 36 a group of junior officers in the Imperial Japanese Army attempted to overthrow the civilian government and assassinate Prime Minister Okado. The coup failed and a number of the perpetrators were executed. This incident, however, had the strange consequence of causing the military to tighten its control of the government, which helped ensure that military solutions to foreign policy issues would take precedence over diplomatic answers. This ascendance of the military to ever-greater political control prompted the Japanese to pressure the Chinese government for more concessions. When Nanjing refused further concessions, a dispute on the Marco Polo Bridge in Beijing was used as a pretext for a full invasion. The Japanese army made short work of Jiang Jieshi's forces, forcing him out of the capital of Nanjing, and killing some 250 000 civilians in the weeks after the city fell. Within a year the Japanese army had captured much of the Chinese coast and close to its entire north- east. This aggression clearly threatened US interests in the region and they extended loans to Jiang's government. US businesses also traded oil and steel with the Japanese, which the invaders ate up in larger and larger quantities. Eventually the war with China would cost the Japanese government over $5 million a day. This dependence on US resources would prove to be a serious and strategic liability, one that would propel the Japanese government to war with the US. In essence, the Japanese determined that they needed to expand in order to keep what they had. This expansion would eventually threaten US, British and Dutch holdings in south-east China. Any resources the Japanese could take from the region would be threatened on their journey back to the home islands by the US protectorate in the Philippines. Something would eventually have to give. Wa r plans There is competition between the branches of any military and Japan's was no exception. The army's reputation had been sullied by the attempted coup of 1 9 36, but it was still politically very powerful. The navy, the more conservative branch, had never really taken to the rabid nationalism of the army. All branches of the military want to demonstrate that it is the more vital to the national interest and thus claim a greater influence and share in the distribution of resources. The Japanese army thus argued for a solution that emphasized land operations against the Soviets. This plan, known as the "north programme" was tested in the late summer of 1 9 39 when a Japanese division engaged a Soviet force under the command of Georgi Zhukov on the Mongolian border. The Japanese were overwhelmed and withdrew. From that point, the "south programme" which would push the search for resources and hegemony into Indo - China was dominant. The "south programme" gave more strategic planning influence to the navy. It would also likely clash with western interests in the region. The fall of France in June 1 940 and the signing of the Tripartite Pact with Italy and Germany seemed to open the way for the expansion of Japanese influence into the French colony in Indo-China. With her right flank protected by a non-aggression pact with the Soviets, Japan had by The summer of 1 941 occupied the entire colony. Pearl Harbor The months leading up to the attack on the US naval base in the Hawaiian Islands saw a flurry of diplomatic wrangling between the United States and Japan. The US was determined that Chinese territorial integrity be restored and free trade be reopened. The Japanese were just as determined to not forfeit their recent gains, nor to have their strategic plans are subject to western approval. In July 1 941 the Japanese army occupied all of Indo - China and Roosevelt learned, through radio intercepts, that the Japanese were developing military plans at the same time as they claimed to be negotiating in good faith. Roosevelt ordered an embargo, supported by the British and Dutch, on all trade with Japan. This cut the Japanese military off from over 80% of its oil and much of its steel and had the effect of putting the negotiations with the US on the clock. Japan's oil reserves were low and if war with the US was coming, the faster the better, before fuel shortages made combat impossible. This was the view of the commander of the Japanese Imperial Navy and chief military planner, Admiral Isoroku Yamamoto. Yamamoto had studied in the US and understood its awesome industrial strength and military potential; he hoped that his government could avoid a war with the United States. In the event that such a war did come he believed that the Japanese could be reasonably successful for six months to a year. Should the war continue beyond that, Yamamoto had little confidence that they could win. This formed the outline of Japanese strategic thinking in the fall of 1 941. Should war be necessary, they would act quickly, expanding their empire 's defensive perimeter from which they could negotiate from a position of strength. Yamamoto was tasked with developing the attack plan. It would contain three assaults. The Japanese army would land and overpower the US outposts on Guam and Wake Islands. A larger force would land in the Philippines. The main focus of the operation was a surprise aerial attack on the US naval base at Pearl Harbor. Waves of torpedo and dive bombers would launch from aircraft carriers that had snuck across the Pacific. The goal was to damage the US fleet to such an extent that it could not carry on operations in the Pacific, thereby giving Japan a free hand to consolidate its gains. Surprise was vital for this operation. The ongoing negotiations in Washington and the US Pacific Fleet's tradition of standing down on Sundays gave the Japanese the confidence that this surprise could be achieved. The US Pacific Fleet was indeed surprised. Over two-thirds of the available anti-aircraft guns went unmanned and there was precious little ammunition for those that were. It took a little over an hour for two waves of bombers to sink four battleships and heavily damage three others. Twelve other vessels of varying sizes were also damaged and 200 aircraft were destroyed, most of them on the ground. By the end of the day the US had suffered 2, 700 casualties of which just over 2,000 were dead. While the damage caused by the raid was stunning, it was far from the unqualified success the Japanese needed it to be. Despite what was hit during the raid, it is perhaps more significant to consider what was not hit on 7 December 1 941. The US aircraft carriers had not been in Pearl Harbor that morning and their survival meant that the US could regain the initiative in the Pacific in short order. The dockyards and huge oil tanks were not heavily damaged, ensuring that Pearl Harbor was still very much an operational base, able to fuel vessels and repair those that had been damaged. Indeed it is a testament to the industrial strength of the US that of the four battleships sunk at Pearl Harbor that morning two were raised and repaired within two and a half years.
