The devil is cast out into the earth for the final 3½ years, correct?

Revelation 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

Isn't it the final 3½ years, because of these two lines in that same chapter?

Revelation 12:6 And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.

 14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.

As a side note, don't folks who are post-trib say that there is no blessed hope before the tribulation, as there is no escape?

However, won't those Israelites, who are kept safe in the wilderness, indeed escape the horrors of the tribulation?

Anyway, does it not seem that some people do not escape what is coming, but by contrast, some must then escape?

I Thessalonians 5:3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.

 4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.

 9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,

Some do not escape, but some do, correct?

Luke 21:36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.

Why would Jesus say that, if no one was going to escape?

By the way, I have another question:

Revelation 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

 10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.

Does that mean, that prior to the final 3½ years, the devil will be accusing us before God?

For those of us who will be there, will he hear, and experience, our being accused?

The LORD has forgotten our sins, but there is no indication that the devil forgets them.

Will he, at that time, be bringing up everything that we have done, including those forgiven sins, forgotten by the LORD?

Even though the devil sounds to be the ultimate prosecuting attorney, accusing us, there is still a good thought:

I John 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:

I still have one more question:

Revelation 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.

When the devil is cast out into the earth, does he have a crash landing?

What if, instead, he descends slowly, landing on his feet?

What if he attempts to deceive, by imitation, and descends upon the mount of Olives?

What if, at that same time, he looks like those pictures of a long-haired, effeminate European with a beard, that the world thinks is Jesus?

Am I mad, or could these things happen?
