Daniel 9:
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
The he of verse 27 has to refer back to its nearest antecedant- which is the prince of the people who will destroy the sanctuary. So it is a ruler of Rome. whether of the time of Danile, Jesus ,or when He arrives is to be seen.
But as this is future is clear:
Matt. 24:
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand
16 Then let them which be in Judaea flee into the mountains:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
That this was not the 70 AD judgment against Israel for the unpardonable sin is clear. First in that 4 years Rome did not defile the holy place.
Second while the destrtuction of Jerusalem was horrid, Israel was basically spared (as evidenced they could gather an army for the 130's bar Kochba revolt) and we have had worse troubles in the world since then.
As this refers tot eh antichrist is also clear elsewhere:
2 Thessalonians 2:3-4 King James Version (KJV)
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
Also Rev. 12 shows the antichrist breaking the 7 year covenant with Israel midway through. Israel fleeing and being protected by God for 3 1/2 years So this is the fulfilment of Daniel 9 and Matthew 24
