Okay, let's step back because this is getting silly. My purpose in this thread, to which you have frequently referred, is to challenge the idea that God has ever made false or unfulfilled prophecies. An idea which I frankly consider blasphemous. Your argument is that God has done this because, as in the case of Jonah, God said that Nineveh would be destroyed and it was not. My argument is that this is an overly restrictive view of the prophesy in that here and elsewhere, the implication is that if the object of the prophesy repents, the punishment will not be carried out. This is the conditional part. To point out that a statement did not prove literally true, such as in Jonah, is an unfulfilled prophesy only if we ignore the conditional nature of the statement.
That is how I brought the idea of "conditional" into the conversation. How this translates into the question "is the future conditional" I don't know. Ultimately it is not, but this does not mean that God will not act in a given way based on what he knows will be the reaction of the person(s) acted upon. To that extent, I am sure there are "conditional" events out there, just as there were in Biblical times.
