amount to very much. The other Allies pushed back hard against Japan's efforts to dominate China through the Twenty-One Demands of 1915. Its occupation of Siberia proved unproductive. Japan's wartime diplomacy and limited military action had produced few results, and at the Paris Versailles peace conference. At the end of the war, Japan was frustrated in its ambitions. At the Paris Peace Conference in 1919, its Racial Equality Proposal led to increasing diplomatic isolation. The 1902 alliance with Britain was not renewed in 1922 because of heavy pressure on Britain from Canada and the United States. In the 1920s Japanese diplomacy was rooted in an largely liberal democratic political system, and favoured internationalism. By 1930, however, Japan was rapidly reversing itself, rejecting democracy at home, as the Army seized more and more power, and rejecting internationalism and liberalism. By the late 1930s it had joined the Axis military alliance with Nazi Germany and Fascist Italy. In 1930, the London disarmament conference angered the Imperial Japanese Armed Forces. The Imperial Japanese Navy demanded parity with the United States, Britain and France, but was rejected and the conference kept the 1921 ratios. Japan was required to scrap a capital ship. Extremists assassinated Japanese Prime Minister Inukai Tsuyoshi in the May 15 Incident and the military took more power, leading to rapid democratic backsliding. Japan seizes Manchuria In September 1931, the Japanese Kwantung Army—acting on its own without government approval—seized control of Manchuria, an anarchic area that China had not controlled in decades. It created the puppet government of Manchukuo. Britain and France effectively controlled the League of Nations, which issued the Lytton Report in 1932, saying that Japan had genuine grievances, but it acted illegally in seizing the entire province. Japan quit the League, Britain and France took no action. US Secretary of State Henry L. Stimson announced that the United States would also not recognize Japan's conquest as legitimate. Germany welcomed Japan's actions. Towards the conquest of China The civilian government in Tokyo tried to minimise the Army's aggression in Manchuria, and announced it was withdrawing. On the contrary, the Army completed the conquest of Manchuria, and the civilian cabinet resigned. The political parties were divided on the issue of military expansion. Prime Minister Tsuyoshi tried to negotiate with China, but was assassinated in the May 15 Incident in 1932, which ushered in an era of nationalism and militarism led by
