I have seen some discussions related to the "Kingdom" book, and the recent studies, but, I didn't see the one pertaining to the second chapter of the "Kingdom" book. I may have missed it. If I have ...mea culpa.
Chapter 2, paragraph 29 & 33
29 Long before 1914, the Bible Students said that a time of trouble would begin in that marked year. But even they could not have imagined how accurate that prediction would turn out to be.
33 Unfulfilled expectations were another test. Though the Watch Tower had rightly pointed to 1914 as the year when the Gentile Times would end, the brothers did not yet understand what would take place in that year.
Ok. The first point is, when using the actual paper publication, paragraph 29 is on the top left and paragraph 33 is top right. So you can see both points without turning the page. Simultaneously. So there is no excuse.
Par. 29 makes the point that they were "accurate" in their "prediction". So, obviously, 'they knew it all'. Yep. Brilliant people those. So well did these ones knew the future, that they could publicly tell out a "PREDICTION".
(Note that the book says they made a "prediction", something Jehovah's witnesses say they don't do when defending their failed predictions.)
But according to paragraph 33, a few paragraphs later, these oracles 'hadn't a clue' what the hell was going to transpire in1914.

A complete contradiction.
And how a bout a fat lie.
Watchtower magazine July 15, 1894 (226-231) under the heading "CAN IT BE DELAYED UNTIL 1914?"
We see no reason for changing the figures-nor cold we change them if we could. They are, we believe, God's dates, not ours. But bear in mind that the end of 1914 is not the date for the beginning, but for the end of the time of trouble. We see no reason for changing from our opinion expressed in the view presented in The Watch Tower of January 15, '92. We advise that it be read again. (italic original)
The Watchtower of January 15, 1892 page 19-21) 
VIEW FROM THE TOWER
The Scriptures give unmistakable testimony... that there is a great time of trouble ahead... anarchy and terror, and prostrate humanity in the very dust of despair... out of that confusion... the new rule of righteousness. All this the Scriptures show us, is to come to pass before the year 1915 ((See MILLENNIAL DAWN, VOL II., CHAPTER IV.)-- that is, within the next 23 years.
...the daily papers and the weeklies and monthlies... continually discussing the prospects of war in Europe. They... predict that war is inevitable.... But notwithstanding these predictions and the good reasons which many see for making them, we do not share them. That is, we do not think that the prospects of a general European war as so marked...
The Watchtower has written so many lies. So very many lies. How could anyone trust them for anything.
