What was one of the main goals of Japanese Militarism in the early 20th century?

One of the main goals of Japanese Militarism in the early 20th century was to transform China into a slave state for resource extraction. This ambition stemmed from Japan's desire to expand its empire and secure vital resources to fuel its rapid industrialization and military ambitions. In the context of rising militarism, Japan sought to dominate its neighbors, including China, viewing it as a source of raw materials and economic exploitation. The invasion of Manchuria in 1931 is a notable example of this imperial strategy, leading to the establishment of a puppet state and significant exploitation of Chinese resources and labor.

The other options do not align with the militaristic aims of Japan during this period. Establishing a democratic government in China contrasts sharply with Japan's aggressive militaristic and imperialistic policies. Promoting peace and international cooperation would be anathema to the aggressive expansionism that characterized Japanese militarism. Similarly, forging a military alliance with the United States contradicts Japan's actions during this era, especially as relations soured leading up to World War II.
