I was of the impression that most Christians, apart from looney Jobots, felt that the prophecy of the last days was about the fall of Jerusalem under the Romans. Whether a secondary fulfilment is expected or not depends on denomination...........or so I'm under the impression of.
The 'Last days' seems to be interpreted differently between and even within the different sects of Christianity.
Whatever the reality, the Watchtower(tm) will definitely be totally wrong!
