In his talk "Peace - Can it Last?" NH Knorr said that the League of Nations would emerge after the War as the United Nations.
It was fulfilment of the Revelation, that the beast "was but is not, yet is about to ascend out of the abyss."(after WW2)
Yet the earlier interpretation was that the Beast came into existence when the Court of International Justice was founded at the Hague in 1903 (?06?).
It then went into the Abyss during WW1, to reemerge as the League of Nations standing in a Holy Place by supporting the British occupation of Palestine, and by claiming to bring peace instead of Gods Kingdumb.
Nowhere in Revelation does the beast TWICE become inactive. This is another case of the Witchtower cutting its sales to the current political situation.
I am not even sure that the relevant verses actually mean what they claim. What did the writer (not John the apostle) mean?
