Any perceived attack might be seen by Jws as the great tribulation. However, an official branding by the Org would be unlikely.
There is one thing we all here need to accept. This religion is not going away. Even if the GB came out and said "Well folks its all BS!!" there would still be some who carry on as if nothing. Hell, there are still people who are Branch Davidians (David Koresh's cult). Unless every witness killed themselves like in Jonestown, this religion is here to stay.
Judaism, Christianity, Islam, Hindu and countless other religions that have survived for thousands of years all started out as cults. Im not saying the JWs are going to be around that long but as long as Christianity is around so will its offshoots. These cults have learned to morph and made necessary changes to become mainstream and popular despite legal or financial troubles. They are no longer "cults" by strict satndars but they are very much cults if the members allows. The JWs are trying to make the leap to mainstream. Within 20 years this religion will have a new GB and who knows the radical changes they will bring.
What I hope to see is what we have seen with other religions, their members not taking the church too seriously. Reforms, acceptance; these are the things I want to see. Of coarse I would love to see this religions (and all religions) demise but as long as there are people willing to let others guide their life and morals there will always be religion and, in this case, Jehovahs Witnesses.
