Hi Band on the Run,
For a balanced view about this matter you can read Dedlef's Garbe Zwischen Widerstand und Martyrium.
To make your own conclusion: read the letter by yourself, read the declaration of facts (yearbook 1934) and
read the history of Jehovah's Witnesses in Germany in the yearbook of 1975 and read the Awake of 22 august 1995.
What I forgot to mention in my earlier post:
Rutherford & Knorr wrote the declaration of facts, but the Yearbook of 1975 gave the credits to P. Balzereit, to blame him, the black sheep of WTS Germany.
In the Awake issue July 8, 1998 the society admits that Balzereit was not the writer.
When I mentioned this all above in the 90's I contacted the WTS HQ in Brooklyn. The answer I got above this issue was shocking.
A staf member arround the GB circle told me that the publications of the society can not always present the truth about JW history, because the average JW can not handle
the new facts. They have to be prevented of losing their belief.
