Just because an organisation has survived problems in the past doesn’t mean it will survive problems in the future. That’s illogical. It’s like saying that because I survived measles as a child, therefore I won’t die of another illness tomorrow. It just doesn’t follow.
Where history is relevant is looking for trends and comparisons. On this front JWs resemble other organisations that have collapsed and many longstanding trends indicate they are in deep trouble. The fact that they may have survived this or other crisis or scandal decades ago is irrelevant to the current situation.
