I think that Revelation is about the Jews.
If Revelation is about Jews it is about spiritual Jews, IOW, it is is about the church. It certainly isn't about the branches that were cutoff because of unbelief.
It could have happened at any time had Israel obeyed but of course they never did. Jesus gave them one last chance, but they rejected him as well.
And guess what that would mean? It would mean the OT has some false prophecies. For example, the following.
Psalms 110:1 Psalm of David.>> The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
Everyone knows or should know if they don't, this prophecy predicted a first coming followed by a leaving, followed by a return. The return is yet to happen, though.
Zechariah 14:5 And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the LORD my God shall come, and all the saints with thee.
And this prophecy predicted a return(which is yet to happen) after His leaving of the planet in order to fulfill Psalms 110:1.
Isaiah 11:4 But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth: and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked.
and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked---compare with---Revelation 19:15 and Revelation 19:21, and also 2 Thessalonians 2:8.
And I'm sure I can find more, but this should be plenty to make the point, that what you said was possible, it was not even possible at all since it would have made God and the prophets He spoke though, out to be liars since none of those things could ever get fulfilled if you are correct. In the OT it predicts a 2nd coming numerous places, except it was hidden until Christ came.
If you are ok with the fact, that if you are right, this would mean that God lied numerous times in the OT, the fact some of these prophecies predict a 2nd coming, by all means then, continue believing that that was a possibility had the Jews not rejected Christ at the time. Not to mention, there goes the 70th week, or at least the last half of it, out the window if what you said could have happened, had it happened. Except it was never possible to begin with and numerous prophecies in the OT undeniably prove it.
One more thing while it's on my mind, before Jesus went to the cross He already predicted He would leave the planet at some point then return at some point. Meaning the parable involving the talents(Luke 19:12-27). And now what you proposed as having been a possibility, would have made Jesus out to be a liar as well.
Isaiah 46:9 Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,
