九一八事變
David Bergamini's book "Japan's Imperial Conspiracy" (1971) has a detailed chronology of events in both Manchuria and Tokyo surrounding the Mukden Incident. Bergamini concludes that the greatest deception was that the Mukden Incident and Japanese invasion were planned by junior or hot-headed officers, without formal approval by the Japanese government. However, historian James Weland has concluded that senior commanders had tacitly allowed field operatives to proceed on their own initiative, then endorsed the result after a positive outcome was assured.
