They want to gain the support from foreign powers who are not familiar with Tibetan issues.
There is hardly any power
more familiar with Tibetan issues than Japan.
The similarity between the Tibetan flag and the Imperial Japanese Army flag is not mere coincidence. Indeed, the 13th evil dalie's incipient Tibetan army was trained by the Imperial Japanese Army. The link between evil dalies and Japan is therefore old.
Before and during WWII, Imperial Japan, at war with China between 1937 and 1945, invaded and occupied huge chunks of China, including the financial metropolis Shangai and the capital Nanking, plus Manchuria and Taiwan, as well as the French Indochina (current Vietnam and Cambodja), Laos, Thailand, and Burma, thus effectively encircling the remaining of China.
Of course Japan attached great importance to, and was well informed about, Tibet, as it was about Eastern Turkestan (Xinjiang) and Mongolia. The 1939 Japanese expedition to Tibet is well known.
Therefore, the current evil dalie requesting Japan, the former invader, dismemberer, and occupier of much of China, to “help” with Tibetan “autonomy” is a bad taste joke, and an obvious provocation against China.
Such provocation is done because the evil dalie is a sad US-salaried puppet, as the 13th evil dalie was a sad Britain-salaried puppet, and the US wants to increase and exploit the ongoing rift between China and Japan in order to foster its own hegemonic, destructive interests n Asia.
This is the current evil dalie's “big picture”: to be used as a tool by a chaos-spreading nation (US) hell bent on creating division and war among Asian countries, while promoting his own petty local interests.
