It hasn't and probably won't be... :o)
When has The AntiChrist appeared and set his image up in the rebuilt Temple?
70AD
When and where has Christ bodily appeared and set up His 1,000 years of perfect peace?
Where does it say He will? :o) Literal vs. symbolic interpretation here, of course.
When has 1/3 of the seas; 1/3 of the rivers; 1/3 of the human population of the world become as blood or died?
symbolic again
When has the Mark of The Beast been implemented world wide by a world wide government in ancient times?
The kind of mark you're referring to hasn't and won't.
When have there been so many "signs in the heavens--manmade and otherwise--in ancient times?
What signs are you referring to here? UFO sightings?
As to armies of horses. . . as I recall, the Scriptures about those have to do with Russia. Regardless, many have boggled skeptically at Biblical predictions before. Didn't slow God down one microsecond. He STILL did what he said He would. And He still will. . . regardless of whether it matches your theology or mine.
Russia will come into Israel through Iran? Long way around, especially for 100 million horsemen. Only China has that many soldiers, which in the past I had always interpreted to be a potential fulfillment of that scripture. Regardless, how many troops would it take to occupy something the size of Israel? 100 soldiers for each 3 current citizens? How would you feed and water that many horses?
The answer is to see the symbolism throughout much of the Bible and interpret Revelation in that light.
But my memory has it that the Scripture about 100,000,000 million troops and the Scripture about horses are different Scriptures. I don't recall a Scripture about a 100,000,000 strong calvary.
I'm sorry you're perspective is so handicapped by being chained to symbolism for some strange reason. . . comfort?
