Then why was the 100 (so far) year reign in between the two events not foretold? According to JW lore
They originally taught that they were living in Christ's millenial reign so when they changed this teaching this is one of the unanswered questions that arose. They used to call one of their magazines 'the Golden Age'. I think this Golden Age refers to the Millenial rule in which they were then living. When you tell a lie you forget that you have to keep telling more lies to cover all your basis.

To add to the confusion, the Society teaches that Jesus was enthroned as King in 1914. The Society still uses the phrase "Millennial Reign" to refer to Jesus' reign. So how he could have been enthroned as King and not start his Millennial Reign in 1914?
Of course, originally the belief was that Jesus became king in 1878 with the Millennium starting before or on 1874, so the Millennial Reign was supposed to be underway when Jesus became King, not after a very long delay afterward. Then in 1925 Rutherford updated the date of Jesus becoming King to 1914, with hints in the "Millions Now Living" campaign that the Millennium would begin shortly, e.g. in 1925. Then with the passage of time, the Millennium became indefinitely postponed with the date of Christ's enthronement stuck to 1914. The more time passes, the greater the disparity between the two becomes.

Once again it is just so difficult to make any sense out of teachings that don't add up.
