Is a 'Free Tibet' a possibility?

The rallying cry "Free Tibet" can even be observed in the caps worn by
the down-and-outs begging for nickles and dimes in the streets of
Vancouver downtown.  I wonder how many of them are able to show where
Tibet is on map.  But let us see how possible (or probable) it is for
a 'Free Tibet' to materialize.

There are 58 ethnic groups in China and the Tibetans are not even the
largest one. The attempt to restore a 'Free Tibet' in accordance with
the Dalai Lama's formula, which encompasses about 1/4 of China's
current territory, would mean having to walk over the dead bodies of
the other 57 ethnic groups.

"The Dalai Lama's stated aim is for Beijing to grant some kind of
limited autonomy to Tibet......... has been that the new autonomous
region would include so-called "greater" Tibet, that is, all the
traditionally ethnic-Tibetan areas now parts of the provinces of
Sichuan, Yunnan, Gansu and Qinghai. In total, that would compromise
around a quarter of China's current territory. No government in
Beijing could ever contemplate such a giveaway, which would almost
certainly unleash a nationalist backlash of frightening proportions."

Territorial claims have to be practical to make any sense.
Vietnam and Mongolia proper were once parts of China for a millennia.
Korea used to rule northern China for a quite a while.  Other examples
are the Manchus' rule over Manchuria, Uygurs had their empire for a
millennia too..Baikal Lake was called a Northern lake in China.
Tibetan empire was once so powerful that it ransacked Han capital
too.  The whole human history has been the history of empires gobbling
up each in much the same way animals eat up each other in a jungle.
Dalai wants to go back to past history of hundreds if not thousands of
years and start from there.  Well, many many years ago Tibetans might
not have been the original inhabitants of Tibet either.  The Nazis
went up to visit them in order to find out if they had been the
ancestors from the vanishing island of Atlantas.

At this moment there are about 80K Tibetan exiles.  Many of them are
the descendants of the former slave owners.  Let them go to Canada or
USA for good since the latter's governments love them so much.  For
these 80K Tibetans exiles to establish an autonomous region equal to
the size of 1/4 of China, they have to walk over the dead bodies of
the other 57 ethnic groups scattered everywhere.

Who would take the lead?  Perhaps the down-and-outs in Canada, or
Europe...or the beach bums in Australia.. would do so.  After all,
they don't have much to do anyway.  Thus shouting some slogans while
being unable to point out where Tibet is on map should be a very good
Sunday pastime....
