The difficulty in the U.S. is that the legal system does not like handling cases that involve "religious freedom" because of a fear of infringing on the Constitution and Bill of Rights. It is only when the conflict involves a violation of civil rights that it is forced to deal with these issues. The Watchtower Society has resorted to legal threats to discourage individuals from pursuing these cases. It realizes that most victims have only limited financial resources to fight back. In contrast, the Society maintains a battery of lawyers and unlimited finances at its disposal.
I don't think the Watchtower Society is going to "go away" any time soon. It may, in time, adjust its views and moderate its position. But this will take years to accomplish. Undoubtedly, there will be more scandals and revelations that will cause some to leave the organization. But this is always counterbalanced by the new converts that come in. But nothing in life is completely static. Eventually, changes will come. And then, perhaps, as James Penton suggested that Jehovah's Witnesses will be just another "denomination among denominations."
