24 they will fall by the edge of the sword, and be led captive among all nations; and Jerusalem will be trodden down by the Gentiles, until the times of the Gentiles are fulfilled. (Luke 21:24)
As I see, a natural reading of this prophecy says that if we see Jerusalem, the city, without being trodden down by the Gentiles, the times of the Gentiles will be fulfilled. However, many years ago, Jews returned to Jerusalem and this city is no more trodden down by the Gentiles.
It seems that Luke added this verse after Jerusalem was destroyed by the roman armies, so he thought that Jews could not govern there until Jesus' second coming. Furthermore, "orthodox" church fathers of the second century believed that Jerusalem would be rebuilt by Christ and he would reign there for 1000 years.
So, as I see, this prophecy was not fulfilled.
