I think that you are trying to turn a judgment message into a prophesy.
(Ezekiel 4:4-7) 4 “And as for you, lie upon your left side, and you must lay the error of the house of Israel upon it. For the number of the days that you will lie upon it you will carry their error. 5 And I myself must give to you the years of their error to the number of three hundred and ninety days, and you must carry the error of the house of Israel.
6 And you must complete them. “And you must lie upon your right side in the second case, and you must carry the error of the house of Judah forty days. A day for a year, a day for a year, is what I have given you. 7 And to the siege of Jerusalem you will fix your face, with your arm bared, and you must prophesy against it.
This is from the "The Nations Shall Know I am Jehovah" - How?

13 That the destruction of Jerusalem was to be in punishment for the religious error of his chosen people, Jehovah directly stated to Ezekiel, who was depicting the siege of Jerusalem, saying: “And as for you, lie upon your left side, and you must lay the error of the house of Israel upon it. For the number of the days that you will lie upon it you will carry their error. And I myself must give to you the years of their error to the number of three hundred and ninety days, and you must carry the error of the house of Israel. And you must complete them.”—Ezekiel 4:4-6.
14 By this Ezekiel was to indicate, not the length of the coming siege of Jerusalem, but the exact year in which the city was to be destroyed, at the end of its siege. The expression “the house of Israel” here stands for the Northern Kingdom of ten rebellious tribes of Israel, which did not recognize Jerusalem as its capital. Nevertheless, Jerusalem was held accountable for the religious error of the Northern Kingdom of Israel, because, from the closing years of King Solomon, that city had given all twelve tribes of Israel a bad religious example, toward idolatry.
Please contact a local Witness and ask to see Chapter 6 of the above book.
The times he laid sides marked the number of years from the start of their apostasy to their judgment. The 40 days pointed to the time when the desolation of Jerusalem would start, which was after Ezekiel completed the drama.
Edited for your comments.
Yes, it was a prophesy, but for the nation of Judah, showing exactly how long before their destruction would come.
And as you know, we never look beyond the next year even, as we keep in expectation of the Lord's Day of judgement for the earth. Since the Know Jehovah book was published almost 3 decades before the end of the 20th century, we continue to "seek first the Kingdom".
And if you know this book already, why float some strange expectation that ignores Jesus' words about the time of the gentiles, and his references to the book of Daniel.
(Matthew 24:15-16) 15 “Therefore, when YOU catch sight of the disgusting thing that causes desolation, as spoken of through Daniel the prophet, standing in a holy place, (let the reader use discernment,) 16 then let those in Ju·de′a begin fleeing to the mountains.
And yes to your other questions. Jehovah's Witnesses do carry on the ministry that Jesus gave his disciples, and as such are the physical part of Jehovah's organization. That is why and how the great dragon can try to wage war against the ones bearing witness about Jesus, since he can't touch any of them that are in the heavens.
(Revelation 12:15-17) 15 And the serpent disgorged water like a river from its mouth after the woman, to cause her to be drowned by the river. 16 But the earth came to the woman’s help, and the earth opened its mouth and swallowed up the river that the dragon disgorged from its mouth. 17 And the dragon grew wrathful at the woman, and went off to wage war with the remaining ones of her seed, who observe the commandments of God and have the work of bearing witness to Jesus.
(2 Corinthians 5:20-21) 20 We are therefore ambassadors substituting for Christ, as though God were making entreaty through us. As substitutes for Christ we beg: “Become reconciled to God.” 21 The one who did not know sin he made to be sin for us, that we might become God’s righteousness by means of him.
Ambassadors act at the direction of their government and delivery messages to the other ruling powers. This is the message that we carry, to all peoples of the earth, to accept the rightful rulership that God has given Christ.
(Psalm 2:1-12)
Why have the nations been in tumult And the national groups themselves kept muttering an empty thing?
2 The kings of earth take their stand And high officials themselves have massed together as one Against Jehovah and against his anointed one,
3 [Saying:] “Let us tear their bands apart And cast their cords away from us!”
4 The very One sitting in the heavens will laugh; Jehovah himself will hold them in derision.
5 At that time he will speak to them in his anger And in his hot displeasure he will disturb them,
6 [Saying:] “I, even I, have installed my king Upon Zion, my holy mountain.”
7 Let me refer to the decree of Jehovah; He has said to me: “You are my son; I, today, I have become your father.
8 Ask of me, that I may give nations as your inheritance And the ends of the earth as your own possession.
9 You will break them with an iron scepter, As though a potter’s vessel you will dash them to pieces.”
10 And now, O kings, exercise insight; Let yourselves be corrected, O judges of the earth.
11 Serve Jehovah with fear And be joyful with trembling.
12 Kiss the son, that He may not become incensed And YOU may not perish [from] the way, For his anger flares up easily. Happy are all those taking refuge in him.
