I don't know. Some in Israel are determined to rebuild the temple, even now. The worldwide kingdom capital will be Jerusalem. There will be a need for facilities for the administration of world affairs, if not an actual throne inside a final temple, eventually.
I don't share the preterist's view of where we are in the timeline of events by any stretch. I think we've entered the final years of this age, and the boomer generation is THE generation referred to in many prophecies. All hell is about to break loose in this world, I'm afraid.
