The WTS can put a new slant on 1914, and it will be swallowed.
Each time there is a change in teaching, they never say "this is what WE used to teach, but now -- :"
They just give a talk or article with the change, knowing that the majority can't even remember the public talk ten minutes later most weeks. The rest are too lazy or stupid to want to check any thing.
After all, "The time of the end" started in 1799.
Changed to 1874.
Changed to 1914.
I can already hear it "Yes, brothers, Christ came to kingdom power in 1914, and all the evidence indicates that he condemned this wicked system to destruction in (1934, you name the likely year) since when have we not seen abundant evidence that we have been in the time of the end. Is it not happifying to know the end is now nearer than ever before as Jehovah's active kingdom government acts to save all kinds of men from a twisted generation?" (cue applause)
