The one thing I have learnt with the Watchtower over the years is that they always give themselves wriggle room.
They will post two completely opposite statements sometimes, so that they can always point to the correct statement when it comes true. They also have said that prophesy can best be understood when it is actually fulfiiled, which actually means they can select the best scriptures to prove something was said years ago that has now been fulfilled.
It has been said that you can make the bible say whatever you want, and the Watchtower society regularly does that.
