I don't think one should characterize either Antiochus Epiphanes or the Roman destruction of the Temple as "blips". These were very significant events. But to respond to your OP:
1. The idolatry of the Jews should not be put on the same level as the desecration of the Temple by Gentiles. The first was sin, the second was judgment. God allowed the Temple to be destroyed by Nebuchednezzar as a judgment. He also allowed it to be desecrated by Antiochus and again destoryed by the Romans as a judgment against Israel. We need to distinguish between things which differ.
2. Antiochus may be taken as a "type" of the Antichrist but with some serious reservations. If one examines his actions closely, they hardly come up to the level of evil and blasphemy which will go forth from the Antichrist.

Job8, I am confused. Antiochus was a very dangerous and evil creature; and combined with his allies, including the self-serving Jews of his days, caused all sorts of havoc. Tens of thousands of Jews--those who would not submit to his demands--were massacred or sold into slavery. You can read all about his evil in Ezekiel 38 and 39, in Daniel, and in the books of the Maccabees.
Where can I find anything in the scripture about a so-called Antichrist?

3. The destruction of the Temple in Jerusalem did not mark the end of Daniel's 70th week. If we read Daniel 9:25,26 the crucifixion of Christ (Messiah shall be cut off) marked the end of the 69th week.
No. Christ did not arrive until the end of the 69th week, or the beginning of the 70th week, depending on how you want to phrase it:
". . . from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks.. . " --Dan 9:25"
That much is crystal-clear. Christ was killed (cut-off out of the land of the living) about 3.5 years later, or half-way through the 70th week, thereby becoming the
ultimate and final sacrifice. At that time the veil of the temple was rent because it was no longer needed:
"… in the midst of the week he shall cause the sacrifice and the oblation to cease…" --Dan 9:27"
During his ministry Christ confirmed the covenant with the (faithful) children of Israel:
". . . Jesus Christ was a minister of the circumcision [children of Israel] for the truth of God, to confirm the promises [the covenant] made unto the fathers:" -- Rom 15:8
"Your father Abraham rejoiced to see my day: and he saw it, and was glad." -- John 8:56
"Blessed be the Lord God of Israel; for he hath visited and redeemed his people, And hath raised up an horn of salvation for us in the house of his servant David; As he spake by the mouth of his holy prophets, which have been since the world began: That we should be saved from our enemies, and from the hand of all that hate us; To perform the mercy promised to our fathers, and to remember his holy covenant; The oath which he sware to our father Abraham," -- Luke 1:68-73
"My sheep hear my voice, and I know them, and they follow me:" -- John 10:27
"But he answered and said, I am not sent but unto the lost sheep of the house of Israel." -- Matt 15:24
His disciples confirmed the covenant for the remainder of the week, which concluded when the first Gentile was allowed into the Commonwealth of Israel:
"He that receiveth [my disciples] receiveth me, and he that receiveth me receiveth him that sent me." -- Matt 10:40
"These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel." -- Matt 10:5-6
"Ye are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in thy seed shall all the kindreds of the earth be blessed. Unto you first God, having raised up his Son Jesus, sent [Jesus] to bless you, in turning away every one of you from his iniquities." -- Acts 3:25-26
"And God spake on this wise, That [Abraham's] seed should sojourn in a strange land; and that they should bring them into bondage, and entreat them evil four hundred years. And the nation to whom they shall be in bondage will I judge, said God: and after that shall [Abraham's seed, Israel] come forth, and serve me in this place. And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob; and Jacob begat the twelve patriarchs." -- Acts 7:6-8
"Unto which promise our twelve tribes, instantly serving God day and night, hope to come. For which hope's sake, king Agrippa, I am accused of the Jews." -- Acts 26:7
"I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin. God hath not cast away his people which he foreknew. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel saying," -- Rom 11:1-2
"James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting." -- Jas 1:1
"Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied." -- 1Pet 1:1-2
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;" -- 1Pet 2:9
This is the promise to the faithful of Israel, from the days of old, that Peter confirmed:
"And now if ye will indeed hear my voice, and keep my covenant, ye shall be to me a peculiar people above all nations; for the whole earth is mine. And ye shall be to me a royal priesthood and a holy nation: these words shalt thou speak to the children of Israel." -- Exo 19:5-6 LXX
Many Gentiles have hijacked that promise, and claim it as their own. But the promise, and fulfillment, was only to the few faithful and chosen children of Israel.
Remember, Christ's sheep
heard his voice, and they were few. The rest were carried away by strange Gods and were destroyed from amongst the children of Israel, as prophesied, when they refused to hear Jesus:
"I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him." -- Deu 18:18-19
"For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people." -- Acts 3:22-23
So, the covenant was confirmed in the first century. But arduous students of the Bible will note that the covenant confirmation continued far longer than 7 years--for about forty years--because the Lord is longsuffering:
"The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance." -- 2Pet 3:9"
The Gentiles have hijacked that passage, as well.
But, eventually, the days of vengeance for the blood of the prophets could be delayed no longer, and Jerusalem and the temple were destroyed, along with most of the children of Satan who controlled the Jewish people (most, but unfortunately, not all):
"Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it." -- John 8:44
"Therefore also said the wisdom of God, I will send them prophets and apostles, and some of them they shall slay and persecute: That the blood of all the prophets, which was shed from the foundation of the world, may be required of this generation; From the blood of Abel unto the blood of Zacharias which perished between the altar and the temple: verily I say unto you, It shall be required of this generation." -- Luke 11:49-51
"And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. For these be the days of vengeance, that all things which are written may be fulfilled." -- Luke 21:20-22"
All that vengeance and destruction
was not part of the seventy weeks of Daniel, but was
decreed (determined)
separately:
". . . and unto the end of the war desolations are determined." -- Dan 9:26"
". . . and to the end of the war which is rapidly completed he shall appoint the city to desolations." -- Dan 9:26" LXX
4. Christ spoke specifically of the Abomination of Desolation spoken of by Daniel the prophet (Mt 24:15) but He also linked it to the Great Tribulation (Mt 24:21). Indeed, the first would be the cause of the second, since the abomination (image of Antichrist) would result in desolations produced by God's wrath against all the blasphemy.
Actually, it was the arrival of the pagan Roman armies on the holy land of Israel that was the abomination "standing where it ought not." Jesus gave us a clue that is hard to miss:
"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: ) Then let them which be in Judaea flee into the mountains:" -- Matt 24:15-16
"But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that be in Judaea flee to the mountains:" -- Mark 13:14
"And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Then let them which are in Judaea flee to the mountains; " -- Luke 21:20-21
Personally, I do not see how any student of the Bible can miss that, unless they have an agenda that circumvents (blinds) their view.
5. Since the Great Tribulation is future (nothing in world history indicates that cosmic, catacylsmic, and catastrophic events in the heavens and earth of that magnitude have ever occurred), then it follows that Daniel's 70th week is yet future.
You added words to the Holy Scripture. I do not recommend that. The great tribulation occurred during the generation of Christ and his disciples, exactly when he said it would occur:
"Verily I say unto you [My Disciples,] This generation shall not pass, till all these things be fulfilled." -- Matt 24:34
"Verily I say unto you [My Disciples,] that this generation shall not pass, till all these things be done." -- Mark 13:30
"Verily I say unto you [My Disciples,] This generation shall not pass away, till all be fulfilled." -- Luke 21:32
God, in his own Words, repeats it three times; so there will be no excuse for any false teachings or false prophesies based on the Olivet Discourse (Matt 24, Mark 13, Luke 21.)
6. When all the prophecies are harmonized, Satan will control the whole world through the Antichrist for 3 1/2 years following which the Great Tribulation will devastate the earth for another 3 1/2 years. Thus Daniel's 70th week will be completed in the future.
