The enslavement and dispersion of Jews among the nations in 70 AD was the fulfillment of Jesus prophecy found in Luke 21:20-24
This prophecy was fulfilled and is not slated to happen again.
Conclusion: The Great Tribulation spoken of in Matthew 24, Mark 13 and Luke 21 is prophecy fulfilled, i.e., over and done with.
[20 “However, when you see Jerusalem surrounded by encamped armies, then know that the desolating of her has drawn near. 21 Then let those in Ju·deʹa begin fleeing to the mountains, let those in the midst of her leave, and let those in the countryside not enter into her, 22 because these are days for meting out justice in order that all the things written may be fulfilled. 23 Woe to the pregnant women and those nursing a baby in those days! For there will be great distress on the land and wrath against this people. 24 And they will fall by the edge of the sword and be led captive into all the nations; and Jerusalem will be trampled on by the nations until the appointed times of the nations are fulfilled.]
So, you are saying 'the appointed times of the nations' have ended/have been fulfilled?
If they started in 70, when did they end?

When did or does the following take place:
[ 2 But as for the courtyard that is outside the temple sanctuary, leave it out and do not measure it, because it has been given to the nations, and they will trample the holy city underfoot for 42 months.]
[ 5 It was given a mouth speaking great things and blasphemies, and it was given authority to act for 42 months. 7 It was permitted to wage war with the holy ones and conquer them, and it was given authority over every tribe and people and tongue and nation. 10 If anyone is meant for captivity, he will go into captivity. If anyone will kill with the sword, he must be killed with the sword. This is where it calls for endurance and faith on the part of the holy ones.]
