I believe it's more literal...They now have the technology and power to literally make this happen...
I've read the “Left Behind” series, for example, and Salem Kirban’s books. Although I think there is a beast and a false prophet, etc., there are numerous incidents, and theological points that I disputed when reading them. It's been a while, so don't ask me to regurgitate them right now.
Revelation is presented as a vision (Rev 1:2), so allegorical and metaphorical elements are to be expected, although I believe they predict actual events.
The trick, to my mind, is to distinguish what is to be taken literally, and what is a metaphor for some literal event or person.
The greater trick is to determine how what you read can help you become a better Christian. I think a lot of sincere Christians may fall a bit short on this point.
Therefore, while I have definite views on the book, I also have many questions. I am not at all dogmatic about it.
There are only 2 things that I am dogmatic about: 1) without Christ as your personal Saviour, you are lost and going to a literal Hell, and 2) Jesus is coming again to judge the nations.
Every thing else is details on which I may well be mistaken. In fact #2 is secondary to #1. which is the only thing that really matters.
