I don't think you're gonna find many preachers, or even avid interpreters of Revelation for our time, willing to put any kind of dates. For example, the Book of Revelation talks about the massive and sudden destruction of millions of people. Well, this couldn't have been done in the past by ancient means of warfare, swords and arrows and so forth, and yet now it could be. The Book of Revelation presupposes some kind of world wide communication system. For example, when the martyrs, the two witnesses, are killed in chapter 11 of Revelation , it says the whole world will gaze at their dead bodies.
Asteroids potentially hitting the earth, there's a lot of attention now about that.
A geo-political power or force that could actually control the entire world with global communications. I think you could say a stage has been set, as these interpreters would understand the world scene. That is, Israel does exist. The Israelis do control Jerusalem. Therefore, there's the possibility of other things happening.
