I think you are wrong. 1914 can NEVER be dropped. Sure, you can point to persecution starting in the mid-30s, war in the shape of WWII, starvation, illness, you can chew up some earthquakes - but so much is invested in 1914, I feel WT = JW = 1914 etc., 1914 is stated in the same breath as JW. If you changed THAT, then if not an exodus, then at least a massive indifference would begin. If 1914 was changed, then everything could be changed - life eternal on earth, never dying, resurrection on earth, and what would remain would only be hell, trinity and soul.
