Hanson specifically wrote that In the 1920s, Japan began to translate its growing economic might into formidable military power. Let the record show that the Qing Dynasty in China ceded Taiwan to Japan to conclude the first Sino-Japanese war and Japan and pursuant to the Treaty of Portsmouth which concluded the Russo-Japanese War, Russia evacuated Manchuria and recognized Korea as being under the Japanese sphere of influence. Japan would annex Korea in 1910. Japan began to translate its power to military power decades before Hanson wrote. Your comment has no relevance.
