I understand your view and it is very valid. History has shown us this many times.
The question is, is it different this time.
Keshe is not a one man show. There are many scientist working in this Foundation, and he seams to have a significant amount of backing, and protection.
Protection, he is still alive despite.
Financial backing, he was told to leave Belgium and they shifted their operation within a very short time it Italy.
The Foundation gave away all their patents to just about all countries in the world and teach groups of many countries.
They just gathered scientist from around the world to Italy for about a year, who in turn agree to teach in there countries.
Keshe does not go into spiritual subjects very often, but when he does you will realize he is highly connected.
