Which is false!
The prophecy was given in Daniel 9:27 and was quoted by the Lord in Matt.24:15, which means that this event had not yet taken place and was yet future. Then you have no fulfillment of the characteristics of those events mentioned in between the time that Jesus quoted Daniel up to the destruction of the temple. Since all scriptures must be fulfilled, then there must be a future temple, sacrifices and a setting up of an abomination.
Those events regarding the abomination of desolation is speaking a future fleeing from Jerusalem and Judea, which is mentioned in both Matt.24:15-22 and Revelation 12:6, 14. In the middle of the seven years, after the dragon/Satan and his angels are finally cast out of heaven, the dragon/Satan will pursue the woman/Israel, who will flee out into the wilderness where she will be cared for 1260 days, which is that last 3 1/2 years of that seven year period mentioned in Daniel 9:27. It is at the beginning of that last 3 1/2 years when the anichrist/beast/man of lawlessness, will set up that abomination which is what causes Israel to flee out into the wilderness. At the end of that 3 1/2 years is when the Lord returns to the earth to end the age and establish His millennial kingdom. This is another reason why Daniel 9:27 could not have already have taken place, because the seven years ends with Christ returning to the earth to end the age and regardless of what the Amills believe, that has not yet happened.
