Is there any way to change history to get Tibet and/or Mongolia to join the Axis during World War Two or during the Sino-Japanese War in the late thirties? If possible, how much of an impact would it have on the war in China?
Tibet's population at the time was about one million, so it obviously couldn't field a large army, but with German/Japanese supplies and military advisers, it could do some damage. As for Mongolia, although nominally independent during this time period, they were more or less heavily influenced by the Soviet Union so getting them to join in could be hard, but if they did, they could do some damage to the Chinese, especially if they have Soviet weapons.
