Jesus stated that he would come in the clouds after the time of the Gentiles is fulfilled:
Luke 21:24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Luke 21:27 And then shall they see the Son of man coming in a cloud with power and great glory.
He then states when his coming would be:
Luke 21:32 Verily I say unto you, This generation shall not pass away, till all be fulfilled.
Therefore the times of the gentiles ended with the passing away of the generation that heard him speak - simple.

Well, you did leave out a few verses.
So Jesus came with clouds of armies to destroy Jerusalem, then came again AFTER Jerusalem was destroyed?
To....um.....have a resurrection and save the people who were already saved by fleeing Jerusalem before it was surrounded, 3 1/2 years earlier?
----------
But again, John lived to see these things all happen, right?
He saw Jerusalem destroyed, and the ToG's begin, but John didn't see the ToG's end.
Jerusalem was trampled until 1967.
===============================================
It is my opinion, that the apostles expected the resurrection coming to be soon after the dest.. Close enough that they expected, that they might see it. (we who are still alive)
Jesus had told the apostles that Jerusalem would be destroyed, and that there would be a ToG's, But He didn't specify a time in the years of men. That is He didn't say to the apostles, Jerusalem will be destroyed in 35 years or 37 years, as far as we know.
Since the letters of the NT were written before the dest (not Revelation, it's after 70 ad, opinion),
Their writers didn't know how long it would be until the dest. and then how long the ToG's, would last. So they thought they might see the resurrection of salvation.
But the trampling didn't end in 70 ad.
And what was the question, after Jerusalem was destroyed, How long until Israel is restored to Jerusalem and the times of the gentiles end?
The answer is given by the angel in Babylon in Dan. 12:7,
How long? How much time will pass until Israel returns to control of Jerusalem?
Time, times, and a half time, until the power of the holy people is scattered, (70 ad),
(My opinion, How long until Israel is restored to Jerusalem? Time, times, and a half, until the power of the holy people is centralized again, in Jerusalem implied. 1967)
The 7 times equal the time of the statue in Dan 2. The time from Babylon until the restoration to Jerusalem in 1967.
=====================================================
This restoration of Jerusalem is the end of the statue in Daniel 2. The gentile nations that rule over Israel.
The toes/(horns) have ended their control over Israel.
The statue is now complete.
The stone will strike, ...... the strike is imminent, When Jerusalem falls to Iran, the kings of the east.
Then it will be the rapt/resur of salvation, when Jesus comes for the kingdom, and then the end. 1 Cor 15:23-28, 23-24.
