The road to war between Japan and the United States began in the 1930s when differences over [[China]] drove the two nations apart. In 1931 Japan conquered [[Manchuria]], which until then had been part of China. In 1937 Japan began a long and ultimately unsuccessful campaign to conquer the rest of China. In 1940, the Japanese government allied their country with [[Nazi Germany]] in the [[Axis]] Alliance, and, in the following year, occupied all of Indochina. | The road to war between Japan and the United States began in the 1930s when differences over [[China]] drove the two nations apart.
