A big change I think was signalled in their flip flop over Romans 13. The governements are now seen as part of God's arrangement.
Read the old blue school brochure and notice how it was all geared up to how different Jehovah's Witnesses are and how they will not conform or compromise. Then compare that with the much more teacher friendly updated version where the emphasis is very much on how normal and eager to fit in Jehovah's Witnesses are despite their differences. I think that is once instance that signals a general change in attitude.
Another thing is how they changed from not cooperating with outside historians of the holocaust in researching Jehovah's Witnesses in the Nazi period in the 1980s, to actively engaging with the scholarly community in the 1990s.
Anothe thing is they began to seek recognition as a religious body under public la in Germany, a status that did not bother them before.
Broadly agree SBF
It seems the WTS has worked out that politicking and lobbying if you like, is a more powerful way to work your own agenda than doing it all from outside the corridors of power and influence.
From a doctrinal standpoint though I think they may be working towards some significant 'new' ideas - yes/no?
One recent WT article referred to following instructions even if not sure of the reasons its more important to be obedient. For me (apart from the obvious cult overtones) this sounds like an article they may refer back to when introducing something significant that the rank and file may find difficult to digest.
