No, you are not correct. The Matthew 24:16 verse (and Luke 21:21) is for the very END of this present world when the coming false-Messiah to JERUSALEM sets up the "abomination of desolation" idol of the Book of Daniel.
There was NO "abomination of desolation" event in 70 A.D. by the Romans. According to the Jewish historian Josephus (100 A.D.), the 2nd temple burned down while the Romans were trying to get possession of it, a fire having begun inside it.
Thus the Daniel 11 events that the coming Antichrist will do in Jerusalem at the end of this world, for the coming "great tribulation", in a new Jewish temple, will fulfill what that "vile person" is to do with placing the "abomination that maketh desolate" in the new temple, and proclaim himself as God.
Preterism is a false concoction by men. Even a 2nd grader can grasp that the time of the Signs Jesus was giving in Matthew 24, Mark 13, and Luke 21 involving the generation that will see His return is for the END of this world, and NOT back in 70 A.D.
