If one really followed what the text itself says, one would never go so far afield in reaching for latter day "fulfillments".
Most religions, and not just the WTS, have this problem. I believe the term the WTS uses is "parallel fulfillment." Even if the biblical prophecy was intended for a specific time period in the past and was already fulfilled, the WTS always assumes that there will be a "greater fulfillment" which will also be carried out in our day as well. The KofN is a perfect example of this. According to history, this prophecy was already fulfilled. Where does the bible say that it would take place in the future yet once again?
