In order for THE "abomination of desolation" to have occurred in 70 AD or whenever you think it was, then ALL of these Scriptures concerning him would have to have been fulfilled already.
Are you not aware of the importance of Daniel's 70 weeks? (Hint: each week = 7 years)
Daniel 9:22-27
(22) He gave me instruction and talked with me and said, "O Daniel, I have now come forth to give you insight with understanding.
(23) "At the beginning of your supplications the command was issued, and I have come to tell you, for you are highly esteemed; so give heed to the message and gain understanding of the vision.
(24) "Seventy weeks have been decreed for your people and your holy city, to finish the transgression, to make an end of sin, to make atonement for iniquity, to bring in everlasting righteousness, to seal up vision and prophecy and to anoint the most holy place.
(25) "So you are to know and discern that from the issuing of a decree to restore and rebuild Jerusalem until Messiah the Prince there will be seven weeks and sixty-two weeks; it will be built again, with plaza and moat, even in times of distress.
(26) "Then after the sixty-two weeks the Messiah will be cut off and have nothing, and the people of the prince who is to come will destroy the city and the sanctuary. And its end will come with a flood; even to the end there will be war; desolations are determined.
(27) "And he will make a firm covenant with the many for one week, but in the middle of the week he will put a stop to sacrifice and grain offering; and on the wing of abominations will come one who makes desolate, even until a complete destruction, one that is decreed, is poured out on the one who makes desolate."
Daniel 11:31-45
(31) "Forces from him will arise, desecrate the sanctuary fortress, and do away with the regular sacrifice. And they will set up the abomination of desolation.
(32) "By smooth words he will turn to godlessness those who act wickedly toward the covenant, but the people who know their God will display strength and take action.
(33) "Those who have insight among the people will give understanding to the many; yet they will fall by sword and by flame, by captivity and by plunder for many days.
(34) "Now when they fall they will be granted a little help, and many will join with them in hypocrisy.
(35) "Some of those who have insight will fall, in order to refine, purge and make them pure until the end time; because it is still to come at the appointed time.
(36) "Then the king will do as he pleases, and he will exalt and magnify himself above every god and will speak monstrous things against the God of gods; and he will prosper until the indignation is finished, for that which is decreed will be done.
(37) "He will show no regard for the gods of his fathers or for the desire of women, nor will he show regard for any other god; for he will magnify himself above them all.
(38) "But instead he will honor a god of fortresses, a god whom his fathers did not know; he will honor him with gold, silver, costly stones and treasures.
(39) "He will take action against the strongest of fortresses with the help of a foreign god; he will give great honor to those who acknowledge him and will cause them to rule over the many, and will parcel out land for a price.
(40) "At the end time the king of the South will collide with him, and the king of the North will storm against him with chariots, with horsemen and with many ships; and he will enter countries, overflow them and pass through.
(41) "He will also enter the Beautiful Land, and many countries will fall; but these will be rescued out of his hand: Edom, Moab and the foremost of the sons of Ammon.
(42) "Then he will stretch out his hand against other countries, and the land of Egypt will not escape.
(43) "But he will gain control over the hidden treasures of gold and silver and over all the precious things of Egypt; and Libyans and Ethiopians will follow at his heels.
(44) "But rumors from the East and from the North will disturb him, and he will go forth with great wrath to destroy and annihilate many.
(45) "He will pitch the tents of his royal pavilion between the seas and the beautiful Holy Mountain; yet he will come to his end, and no one will help him.
Daniel 12:1-13
(1) "Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; and at that time your people, everyone who is found written in the book, will be rescued.
(2) "Many of those who sleep in the dust of the ground will awake, these to everlasting life, but the others to disgrace and everlasting contempt.
(3) "Those who have insight will shine brightly like the brightness of the expanse of heaven, and those who lead the many to righteousness, like the stars forever and ever.
(4) "But as for you, Daniel, conceal these words and seal up the book until the end of time; many will go back and forth, and knowledge will increase."
(5) Then I, Daniel, looked and behold, two others were standing, one on this bank of the river and the other on that bank of the river.
(6) And one said to the man dressed in linen, who was above the waters of the river, "How long will it be until the end of these wonders?"
(7) I heard the man dressed in linen, who was above the waters of the river, as he raised his right hand and his left toward heaven, and swore by Him who lives forever that it would be for a time, times, and half a time; and as soon as they finish shattering the power of the holy people, all these events will be completed.
(8) As for me, I heard but could not understand; so I said, "My lord, what will be the outcome of these events?"
(9) He said, "Go your way, Daniel, for these words are concealed and sealed up until the end time.
(10) "Many will be purged, purified and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have insight will understand.
(11) "From the time that the regular sacrifice is abolished and the abomination of desolation is set up, there will be 1,290 days.
(12) "How blessed is he who keeps waiting and attains to the 1,335 days!
(13) "But as for you, go your way to the end; then you will enter into rest and rise again for your allotted portion at the end of the age."
The Prophets saw the mountain peaks but not the valleys that lay in between them.
Which is one reason why the disciples thought that Jesus would immediately set up His kingdom in their lifetimes.
