You know.. one of the problems when talking about prophecy and the Jews with Christians is that the concept of prophecy amoung the Jews is different. It is not a foretelling of the future, but rather a message from God, about what is occuring THEN. Usually the prophet sees things gonig wrong, and it attempting to steer the nation of Israel back to the proper path to God.
There are certain things that happen over and over again. Sometimes, things are phrased vaguely enough, it can be adapted to any situation.
Between those two items, the difference in what prophecy is to the Jews, and the difference between prophecy is to the Christians, and
the 'one size fits all' message, you get mixed signals about 'prophecies coming true'.
