However the few experienced Chinese veteran pilots, as well as several Chinese-American volunteer fighter pilots, including Maj. Art Chin , Maj. John Wong Pan-yang , and Capt. Chan Kee-Wong, even in their older and slower biplanes, proved more than able to hold their own against

1118-589: A three-task plan. Task One was the capture of the island of Tulagi in the Solomons. Task Two was an advance along the New Guinea coast. Task Three was the capture of Rabaul.

These competing proposals were resolved by Admiral King and U.S. Army Chief of Staff General George C. Marshall , who adopted

1548-657: The Central Plains War broke out across China, involving regional commanders who had fought in alliance with the Kuomintang during the Northern Expedition, and the Nanjing government under Chiang.

In addition, due to China's fractured political status, Japan often claimed that China was no longer a recognizable political entity on which war could be declared. In Japanese propaganda , the invasion of China became a crusade (Japanese: 聖戦 , romanized:  seisen ), the first step of the "eight corners of the world under one roof" slogan (Japanese: 八紘一宇 , romanized:  Hakkō ichiu ). In 1940, Japanese Prime Minister Fumimaro Konoe launched

2838-430: The 18 September 1931 Japanese invasion of Manchuria marks the start of the War of Resistance. Although not the conventional Western view, British historian Rana Mitter describes this Chinese trend of historical analysis as "perfectly reasonable".

2924-417: The 1921 and 1927 Imperial Eastern Region Conferences reconfirmed Japan's commitment to be the dominant power in the Northeast. The 1929 Red Army victory shook that policy to the core and reopened the Manchurian problem. By 1930, the Kwantung Army realized they faced a Red Army that was only growing stronger.

3526-469: The Chinese to deploy troops in their own city. In Manchukuo there was an ongoing campaign to pacify the Anti-Japanese Volunteer Armies that arose from widespread outrage over the policy of non-resistance to Japan.
