Can it be that the Dalai Lama is losing his grip on his own government in exile? Under ordinary circumstances, when a leader fails to deliver results and live up to his promises, he is usually replaced or elected out of office. The only exceptions are countries which operate under dictatorships and we have observed with the Tibetan case, theocracies. In these situations it is deemed dangerous to be seen to be going against the leader.
Indeed, the question need to be asked if indeed the Dalai Lama has really been ruling his people with the help of the CTA or has His Holiness been relying more on a spirit, Nechung who has been proven to be wrong. If it is Nechung His Holiness has been relying on and not produce results, it would only be natural that the CTA and public would lose confidence but have been too intimidated to speak their mind.
In any case, that Chithue Karma Choephel actually publicly and formally withdrew his support of the Dalai Lama's preferred approach to engaging with China (Middle Way) is a harbinger of changing times and perhaps the Tibetan public and their more responsible representatives in parliament will now begin to challenge questionable policies. This would have to include the Dorje Shugden ban that has done NOTHING good for the Tibetan people nor indeed the Tibetan cause.
The Dalai Lamas have ruled the Tibetans for centuries but as we see time and time again, nothing is permanent, especially an unholy ban on the very enlightened being whom the Tibetan desperately need .
