Back when my PIMI sister would discuss such things with me, we got on the topic of prophecy. She eventually just shrugged her shoulders and said, "Sometimes we can't understand a prophecy until it's fulfilled.
Amazed at the breathtaking incongruity of such a statement, I could only say, "What is the point of a prophecy if you can't understand it until it's fulfilled? Anybody can point to some event afterwards and say, "See! I knew it! I told you so! That's just what I was talking about!""
Just like newspaper horoscopes, if you're vague enough, you can claim to have predicted almost anything.
