Nifty Question but in all reality it doesn't hold much water.
God did not need to reveal anything to Jesus - for Jesus is GOD.
Jesus (in his Glorified self) revealed the Apocolypse to His apostle John.
The prophecy was written by John on the Island of Patmost (a prison Island).
It is historically known and attributed to John.
I'm sure you could try to say that "they" are the Historians and flushed many things down the memory hole and wrote this book - however - they
would have then written the entire Bible, as there are many similarities between the old testiment prophets and the new. Historians will validate the
dates of these documents.
I fear that it is the NEW historians, hell bent on rewriting history, that one needs to worry about.
For those that know the biblical texts (regardless if you believe them) it states that GOD knows the END from the BEGINNING - in other words, God
knows the nature of man and the choices man makes, for it is our nature to deny what is true and to sin against God.
Basically, the book of Revelation is not a "self-fullfilling" prophecy, mankind chose this path back when Adam and Eve sinned.
Jesus said "it is accomplished" on the cross, but man still chooses to sin - it is sin that brings the prophecies to fruition - and God knew it from
He knew mankinds path towards destruction, that is why Jesus came in the Flesh to become the ultimate scarifice.
Read 2 Thessalonians 2:1-12 With Rev. 13 concerning the AC & MOTB
Also here is a great scripture from Peter:
2 Peter 3:3-7
Knowing this first, that there shall come in the last days scoffers, walking after their own lusts,  And saying, Where is the promise of his
coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.(No impacts, no world tribulation,
things are all normal).  For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of
the water and in the water:  Whereby the world that then was, being overflowed with water, perished:  But the heavens and the earth, which are
now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
The "they" that create the MOTB want to for the sake of dissobedience, if they wont do it someone else will - PRIDE was the destruction of Lucifer
(Now saten) and it is this sin of PRIDE that will bring about the events in Rev.
Whew - send me a U2U if you need any clarity
