DO NOT ALLOW YOUR CONFIDENCE TO BE UNDERMINED
A soldier whose loyalty to his leader is weakened will not fight well. So propagandists attempt to break bonds of confidence and trust between a soldier and his commander. They may use such propaganda as: “You cannot trust your leaders!” and “Do not let them lead you into disaster!” To add weight to these attacks, they may cleverly exploit any mistakes those leaders might make. Satan does this. He never gives up trying to undermine your confidence in the leadership that Jehovah has provided.
I think this is about as as close as you can get to the Governing Body admitting they "might" have made errors by the statement "they may cleverly exploit any mistakes those leader "might" make"
